In a recent update, acrobat has an issue with selecting and deleting even or odd pages. When even or odd pages are selected and I try to delete them, it will reset the selection to the first page. If I continue to delete, it will only delete the first page and not the even/odd selection from before. In addition to that, if you deselect the first page before you select even/odd pages in page select, I'm given a prompt that says 'Please choose a valid page range'. If the even/odd page option in the dropdown is selected again, Acrobat now allows me to delete them. Its a very annoying bug that requires 6 clicks when it used to be 2. Attached is a pdf showing the errors and the steps it took to get those errors.
