STEPS TO REPRODUCE
1. Create a new Asset Account  of Type investment without institution assigned (lets name it "Depots", and it shall hold several different (sub) accounts for different brokers)
2. Add a (sub) account, i.e. a child of "depots": name Broker1, account type: INVESTMENT (there is no "Stocks" in the account type selection list available!!!), next, create a brokerage account (or not, is irrelevant), parent account "Depots", Finish:
Name: Broker1
Subaccount of Depots
Type: Investment !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Currency: Euro
Opening date: Samstag, 1. Jänner 2022
Institution: Broker xyz
3. click Finish brings the error message:
Unable to create account: Investment account can only have stock accounts as children C:\_\9b0777e7\kmymoney\kmymoney\mymoney\mymoneyfile.cpp:1019

OBSERVED RESULT
There is no such thing as a "stock account" in the type list when creating a new (sub) account. The list contains: Liability, Asset, Investment, Loan, Cash, Credit Card, Savings, Checking. There is nothing better in the list than "Investment" which throws the above error message.

EXPECTED RESULT
That the (sub) account is created.

ADDITIONAL INFORMATION
The documentation is completely vague, it describes 5 main account types: Asset Liability, Expense, Equity. I see only two types: Assets and Liabilities in my installation. Where is the rest? Not a single word where these Account types are administered, configured, reset. Why are they not existing at all in my installation?
The description of "Categories" is weird. What a category is or for waht it is used is nowhere explained. The pdf manual is really bad for beginners. The basic accounting chapter is childish honestly, balls or beans rolling around in a box .... I think one who installs a personal finance manager to manage his accounts and so on should understand what accounting is, and for a starter with kmyMoney the first at least 30 pages are completely unnecessary. If the handbook is made for users then how about starting with screenshots of a sample setup that contains cash, bank accounts, savings accounts, loans, credit cards, investments, etc. based on a practical outline, i.e. 3 bank accounts, 2 savings, 3 depots, a crypto depot, 2 credit cards, etc. This should immediately show the categorisation of accounts, the tags, and what not, so users without need for reading embarrassing beans statements come to the point. I am aware this is a harsh comment, but would recommend to add a practical example use case as introduction. It is very clear in many passages of the manual that developers wrote the manual, without the reader in mind.
Category is described as a "non-managed income and expense account that do not have a value". I am not sure who may find this helpful, but certainly 99.9% of starters are lost here. Certainly if one develops the concept for years this is a totally clear statement of highest technical nature, but for users this is unusable. Statement of this confusion level are all over the manual.
