SUMMARY
***
In the folder Panel (Folders) some folders that do contain sub0folders do not have a visible arrow, nor does clicking on where it should be expand the folder, and then show the sub folders as it did until very recently  (~ A week or two).
***
Example: my home folder (no others investigated yet), hidden shown, 48 folders in total, 23hidden (with Dot), and 25 not  hidden.  View = hidden on or off,  mode: Icons, "Limit to home directory" = deselected; some of the ones without arrows have only symlinks to other folders in them, some are mixed, and some (most) do not. 

No hidden files with sub folders are missing the arrow, and the fist one missing the arrow is # 33  but stands alone, then they are OK again, and then from #43 on up they all have no arrows.

STEPS TO REPRODUCE
1.  open Dolphin and look.

OBSERVED RESULT
Some folder expansion arrows are missing. 

EXPECTED RESULT

Folders with sub-folders should have visible and functioning tree expansion arrows.,

ADDITIONAL INFORMATION

I am dead tired now, but will investigate commonalities/differences... anything I can notice that may be the culprit.  Sorry, I can't help on the programming end, as it's beyond me.

After startup, Dolphin often does not show all the folder expansion icons. This is corrected by refreshing the view.
Seen on a HDD, but not on an SDD.
