Transfer list gains extra previously owned cards after sales

I'm having a strange issue with my transfer list and the players on it.

After logging in earlier today and relisting my expired items, I noticed that some unlisted items remained on my transfer list. These appeared to be duplicates of players I already had on the list.

At first, I thought it was just a visual glitch that could be fixed by restarting the game. However, the duplicated cards seem to be actual separate items. I'm able to sell both the original card that was already on my transfer list and the duplicated card. I can also store the duplicated or original card in my club.

The duplicated players are shown as "First Owner," even though I have never packed them.

Since I first noticed the issue earlier today, more and more players have appeared as duplicates on my transfer list. This eventually caused my transfer list to exceed the 100-item limit. While the list was over the limit, I couldn't remove items normally, so I had to sell or discard items to get back below 100.

I've attached a screenshot showing some of the duplicated players, as well as screenshots from my gallery showing that I never packed these players. I've also included a screenshot showing 104/100 items on my transfer list. Trying to list additional items while in this state resulted in an error message.

There is nothing specific that I have done to trigger this issue. The duplicates seem to appear on their own, and I'm concerned that this could potentially result in my account being flagged or banned even though I haven't intentionally done anything to cause or exploit the issue.

I'm playing on PC with EA App.

Thanks for the help!
