Selecting multiple pages is challenging with the new version

I scan large quantities of pages. It's easier to scan the entire document, including the front and back, in one scan which leads to many blank pages that must then be deleted. I will also need to extract some of the pages to a seperate docunent by itself. This new version has made this incredibly challenging, less effecient, and time consuming. It's inevitable that I have to highlight.....and rehiglight.....and rehighlight.....and rehighlight the same group of pages because the highlighted pages unhighlight. It's also inevitable that the very first page I highlight is RARELY a part of the export or highlight for reasons that are unknown to me since it is clearly highlighted. Going through and clicking.....every....every.....single.....checkbox..... on.....a.....page.....in......order......to.....highlight/select......a......page......to......delete.....will.....NEVER..... happen.....because ....many..... times......I'm.....selecting.....50+.....pages......in...... each......scan. This new version is absolutely horrible.
