"extra column hover" I think are related to panda theme (but I'm not sure) the other ones I don't know. any suggestions?

You can remove all except 'hover' -- that one is created by a module.

I hate it when modules modify core database tables, but they do that sometimes. And thus making system more fragile and error-prone, specially when those columns do not have default values, are part of keys, etc.

There are a lot of mistakenly made modules for prestashop that modify core tables instead of adding their own tables to database.
Be careful with removing these columns, because the modules will stop working.
The hover column looks like it was added by such a crappy module.
