I have been having a problem with my UI positioning. I've used the UI lock command to unlock and move around the fellowship/raid vitals panel in my interface, locked again and saved the configuration directly after using the /ui layout save <nameofsave> command. So far so good.

However, after a few days, the fellowship/raid vitals actually migrate back to the original place and move closer and closer towards the left edge of my screen, instead of more towards the middle as I intended. Due to me having a quickbar at the left edge of my screen, the raid vitals start to overshadow it. This only happens with fellowship panel 1 and 2 (aka the left side ones), while 4 and 5 actually stay always where I left them.
I of course position them back to where I want them to be. However a few days later, they are at it again.

How can I fix this?

Thanks in advance!
