Filter (default and custom) shows loot but there is nothing

Hello,

When using the default filter and filterblade filter, I can see an icon on the minimap as well as a beam, but there is no text (even when showing all loots). When disabling the loot filter I can still see nothing. Academy map.

Here is a video of the bug in effect

At least it does not look like a mirror :)

Cheers,
