Weird new bug on fleet return messages

This has appeared overnight. On my fleet messages the 'other' tab is not viewable. There were 6 fleet return messages in it this morning, but it wouldn't let me view or delete them on the browser version. Clicking on the tab simply doesn't do anything. If I try to view them on the mobile version is says 'Service Error' and logs me out. The number of messages in this section is growing and I can't view or delte any of them.

It seems to be 2 corrupted messages. The app allows me to delete all other messages from that section as long as the 2 corrutpted are on a different page, not shown. But if it tries to show those 2 messages it quits to login. Desktop browser version just won't show the tab at all, no matter how many other messages are in it.
