Hi,
it was very tricky to see - you had to click on special place... No idea why, but I checked original demo and removed classes they weren't there. It looks like working.
Posted on github but only header files were changed.
Are you aware that version was made for e107 2.2? You are working on site when you lost everything if the core would be updated. And there were important issues fixed too.
I fully recommend using 2.3.3 version, if Gaia is issue, I can make new version.
And frankly, that theme version is so bad written...
