No highlighted items while trading

I dont know why this is happening, but none of my items in my stash got highlighted when im trading. So i have to search every single item, i saw a highlighted border in livestreams, but that's not working for me. Any ideas why? Tried to repair the game, but that's not working either...

I have never really looked into it. This is an assumption on my side.

I think it depends on the message you receive. If the message was copied from the trade site it should highlight the item, if you are on the correct stash tab. Also, maybe it has to be the most recent message you received. If the player writes a custom message, the structure may be different and the highlight might not apply.

Im trading daily and never saw a highlighted item. Dont know why
