Lost my 3 only tradeble players; after completing Hero Upgrade Max 86 SBC

After submitting the hero sbc 3 of my players were gone out my club; Rudiger, Hincapie and Ter Stegen. These were my ONLY tradeble players. I did not submit them into any SBC as I know what I’m doing and I didn’t see them as a concept card as usual after you submitted a player of your squad into a sbc. Also, I’ve seen several players which I’ve submitted into the sbc as concept players to discard. Please fix this EA!!!!
