After last upgrade no primary weapons


As title says, after last upgrade in December ( pc - win 10 , Steam) I’ve no primary weapons. They are in the main back pack in inventory, and can add them to the inventory wheel, but there’s nothing in primary weapons. When I use plundera, all weapons are there but none in primary. Any idea how I cam change this?

Did you use any filtering options?
Please provide a screenshot of your plundra and inventory of the primary weapon page.
