Support No Answer Tabs not appearing Using UIX2 theme

[Xiraa]

I was using forum list tab addon for a while and it was working fine.
Recently I decided to rearrange some of my forums and redo the tabs. So, I deleted all the old tabs and tried creating new tabs.
But they are not showing in my forum.

Here is the forum URL https://forum.xiraa.com/
Can you please let me know how do I get it working again?

Were you using the theme before or you changed it in the meantime ?

I have been using the Same theme from before, It was working fine.
I switched the theme for a minute, and switched it back to the original one, then the tabs were gone! (However made some changes in the theme, from theme option, not any template edits though).
Tried Deactivating and Reactivating the plugins. Deleted Old tabs, and created tabs from scratch, nothing worked.

Sometimes style options leads to changes to the themes.
The theme must be quite intrusive.
