Cards Not Sellable - SDS Help?

[jaylib22_MLBTS]

I have two cards that are not sellable

Curtis Mead - I have Craig Biggio at 2B
Francisco Lindor - I have Trever "TRUE!" Story at SS

1. They are not in the lineup
2. They are not on the bench
3. They have not been added to a collection
4. I only have one squad, so no issue there

I still get the message: This item is currently in use...

Another squad? Events lineup?

They are in a Mini Season lineup. Check those.

Events...even if you don't play Events, a lineup is generated and this is where most people's issues are located.
