Have seen the same thing myself after a copy and paste from one .xml to another, didn't paste over the entire statement and left a " mark at the beginning where I added the replacement statement ending up with 2 next to each otherThe document has 2( "") quote marks when there should only be one(") is what it looks like. Document is probably a .xml document.
If you don't know which document it might be you might want to use the win search function for that particular theater and look for "" in the text.
Oh dearthanks for responses!
I ended up deleting whole theater and reinstalling and that helped
Oh dear
