He actually needs to update ElvUI itself

That version is what I'm using. Since some changes in development version of ElvUI, I unfortunately can't recommend using dev version of SLE anymore. Mostly due to some stuff changed in dev versions and not being present in live version. Seems like you'll have to wait till the next release.

You should take only "ElvUI_SLE" folder from the archive. Did you do that or just dropped whatever was in the archive in the addon folder?

Ok, so I found where it was coming from. Made some adjustments on how size calculation works, cause apparently at some point the function fails to recognize we have more than 2 tabs. Also minimum tab size is now 45, lower sizes could result in tabs with no text. Try alpha version and see if anything...

Can you drop your profile sop I can test it? Seems to be working on my end

Do you have the option to lock chat to the panel enabled? It should be in the general section of chat config

Combo points are not valid for that.

Anything but those will not work.

The option for what you are describing is "UI Buttons Style". It is per character selection.
