This issue was caused by the uninstall password being passed in with characters that are preprocessed.

Password example. 
Pa55w%rD

This password would get processed and changed to
Pa55wrd

The change is reflected in the uninstall logs.

The solution is to change the batch file so it will pass in the literal % so the password looks like:
Pa55w%%rD

This solution will apply to any of the DLP agent tools like logdump service_shutdown that use batch files and passwords.
