Unwanted Page Name Changes

When I get ready to do a takeoff on a job, I separate out the plan pages and name them in a way I can identify them. For instance, I might extract the Life Safety plan and name is "LS". When I upload the file "LS" to zztakeoff, I uncheck the boxes under AI Auto Detect labeled "Page Name" and "Sheet #". Upon uploading, the name of the file gets changed to the number that the sheet was in the PDF I extracted it from (in other words, if there are 10 pages in the construction drawing PDF and LS is the second page, the page gets renamed to "2" in zztakeoff).

I'd like the option to have my file name from my PC carry over to zztakeoff without having to rename it when uploaded.
