lost resistances

Ive been rolling through maps with my 82 max and 86 flat fire res, and than, as i was trying on new gloves and put on my previous ones, i notices, that i`ve lost nearly 30 flat fire res. I decided to check my res withou gear, turns out it`s -35 fire, - 5 cold, +1 light and +19 chaos. Is it a bug or normal? Where did my fire res go?

I did nothing different and there is no res in the tree
