Can you post a screenshot of the layer panel with the hierarchy ob this object?
And please mark, which parts of it are causing the trouble.
Some files are old from recent versions. Some might have a legacy of bugs inherited. It's bad, but it happened in the past.
Is there perhaps Avast Antivirus instlled on your computer? It has been causing issues with messing values in panels.
Well Monika, I'm an idiot.
It I had a hidden guide in there, this was driving me nuts (thankfully not for too long), but opening the layers panel (which I should do more often!!!) thanks to you pointed out the guide which was taking all that space
Thanks a bunch, I have another issue on a separate thread, should you want to have a look at it I would be very grateful
