Memory Usage Increases Exponentially with each Signature

Whenever I or another user in my company uses the Fill & Sign tool to apply a signature or initials multiple times in a single document, the system memory usage goes up by about 10% of the current memory usage.  This gets out of hand really quickly when there are 10+ signatures or initials required and the program will either freeze or crash once the memory usage gets to around 2GB.  I have tried to uninstall using the cleaner tool and reinstalling fresh with no options changed and get the same problem.  I have also tried disabling protected modes and other signature options and nothing stops or slows this rapid memory expansion.  I have tried it on documents with 30+ pages each needing a signature or initial and with 1-page documents with many signatures on the single page with the same result.  This is happening on Windows 10 and Windows 7 machines, when logged into Gmail or not logged in at all.  The only thing I noticed that doesn't do this is if the user types the initials in a text box and only fully signs the document in a couple places.  Any signature added (even the auto-generated signatures) will inflate the RAM usage another 10% or more until the system can't handle it and crashes or freezes.
