I'm a long time lurker on this corner for the internet but I now have a reason to join. I updated from Calibre 3.12 to 3.25 today. I was attempting to convert a pdf to mobi or AZW3 when the issue arose. When converting the page either turns grey or all of the text is "highlighted" in grey. I've tried converting a number of pdfs, including ones I've converted in the past and it's happening to them as well. I've even given converting to epub first and the text is grey as well. If possible I will attach two screen shots to this post.

I've never had an issue like this, I've used Calibre for years and after a few hours of searching and trying different things I've ended up here. I'd rather not have to roll back to to 3.12 if at all possible.I welcome any possible help I can get.
