This only happens on steam toribash not Non-steam toribash.
Everytime I want to load some mods on toribash, like xspar or some big mods, I click on it, and then it says test2.tbm.
So I have to go to game rules remove the test2.tbm and the end just so I can play, Its so annoying.
I don't know how to fix it; I tried uninstalling it from steam(removing the files too) and installing it back,
but it still happens?! Any ideas on how to fix?

It's a bug, currently being worked on. If you wanna play a mod you'd be better off just typing it. Such as /set mod xspar.tbm

yeah. it always happen to me too. the "load" button become "open" but i have the non-steam version

Oh alright, thanks for the tip
