Selling selected gear sell the piece next to it

This is the 3rd time this has happened, I’ll be selling a piece of gear and instead of selling the piece I’m on it will sell a piece next to it. Ive been screwed out of so many pieces of gear I have equilled because I’m trying to make room. It’s VERY frustrating and really starting to piss me off.
Please LOCK any equipped gear from being sold!!!
I tried to capture a video bit my PS4 is set to only go back 30 seconds and it’s just 30 seconds of pissed off confusion
