I cannot confirm this. 

The usermenu of my version of Kile (current snapshot from github, KF5 5.29) works well.

I have also the current snapshot with the same KF5. What happens exactly is the following. I have several user menu items; one of them works as follows, I select some text and the effect is to put this text inside curly brackets. In the window of the user menu I wrote {%M%C}; in order to work correctly I have to select the parameter "Replace selected text"; if not the action is to put the brackets and repeat the text.
The problem is that if I edit this menu the parameter box is never checked, I have to mark it again. If I do not save, the current parameters are kept, but if I do save, then it disappears. It is not grave, only annoying.

Sorry, I still cannot confirm this.

I followed your example and saved the changed usermenu. Restarting kile, opening the usermenu dialog and selecting the added entry, two checkboxes are checked like I defined it.

What is your system you are working on?

I am using Fedora 25, fully updated, using also the kde-redhat repository and my version of kile comes from http://compsci.cas.vanderbilt.edu/Fedora/local/; the owner updates kile quite often and I use the src.rpm file to compile it. 

The user menu works correctly; I attach the user menu edit window I get. The checkboxes are not checked but I do not save it it works as expected. 

Thanks for your interest

I do not have any explanation for this behavior.

The only thing, whichs remains to do, is to take a look at your configuration file 'usuario.xml' (usually in '.local/share/kile/usermenu/'). Search for your entry named 'Llanes' and look for the entries of the checkboxes:

  <menu type="text">
    <title>Llaves</title>
    <text>{%M%C}</text>
...
    <needsSelection>true</needsSelection>
    <replaceSelection>true</replaceSelection>
    <selectInsertion>true</selectInsertion>
  </menu>

Add these lines, if they are not present. But this is just a guess...

Thanks, maybe it is my english to blame! :)
<replaceSelection>true</replaceSelection>
appears as expected. The only problem is that when editing the checkbox still unchecked and if I may any changes I need to do not forget to recheck. Not a big deal.

I have checked that everything works fine with the file example.xml (it doesn't matter if I load it from .local/share/kile/usermenu/ (where I copied) or from /usr/share/kile/usermenu/
I do not see any particular difference from the file example and for the file I created

Another update. After creating submenus, I can check "Replace Selected Text" only if "Needs Selected Text" is checked. Without submenus, it is possible.
