I love this app. I use it on a weekly basis. Since the last update, it lost its capabilities to clear out the superscript numbers. For example, When large numbers are inserted, usually that same number in the same row/column/or block that are marked with a superscript disappears. It is not the case with this latest version. Please fix and update, thanks in advance!
