Make Up a Number Fuction not processing

Question

Kutools Make Up A Number feature does not appear to be working for me. I’ve tested it on smaller number groups and it seems to work fine, but I am looking for a number in a data set of 50 lines and it just says “processing, please wait...” indefinitely. I have many more data sets that I wish to search in that are thousands of lines long so this does not bode well!

Does anyone have any solutions as to why this would be happening? I have other add-ins within Excel but they are often needed so I can't disable them. They're whole numbers, some are positive and some are negative. Please help!
