Defender relay queue will not clear

I have a Relay set up on Fantom with a gas cap of 1200 gwei. The network has been extremely congested over the past couple days, so the transactions were rightfully blocked from going out. However, now I see gas prices have normalized in the ~700 gwei range, and transactions still aren't going out and they're still set for 1200 gwei, which is the limit, instead of the real gas price of ~700.

Is the queue stuck because of all of the older transactions that failed and expired? Why won't they go through? Also, if they do go out, will the entire list of pending transactions go out? This transaction is meant to be triggered on an interval, so it would be a huge waste of gas for them all to go out.
