Missing "show on map" button in quest log

I broke "show on map" button and I tried everything but can't fix it.

I installed the elvui and questie addons, after that the "show on map" button disappeared in the quest log. After that, I deleted all the addons, but the button is still missing. Then I completly deleted and installed back the game client, but the button is still missing.

For some reason, the problem is present only on one character - Sveza from Lordaeron. All my other characters are fine despite using the same addons.

I feel like there is some kind of checkbox "hide the button in quest log" somewhere in game settings, but I cant find it.
I miss the button very much, please help me :(

The quest log currently looks like that

As you can clearly see there is no "show on map" button in top right corner of the window

FIXED!

Update: I managed to fix the issue by this command: /console cvar_default
