Hello everyone,
I will post here to hopefully alleviate any concerns with this. We are aware of this issue and it is something we will look to fix with future updates. Unfortunately it isn't a "simple fix".
To clarify what is happening. On the backend the OL 4 spot is coded differently than the rest of the OL spots. The proper depth charts and players filling the position is still working correctly. OL are playing in the spot. The issue is with the front-end and UI display that makes it appear that there is no one playing OL4 or another player from a different/random position is playing that spot. The devs have confirmed that this is not the case, it is simply a display issue on the front-end.
