Boris FX License Tool Not Removing unlicensed plugins

I’ve run the Boris FX License Tool multiple times and each time I’ve run it, I get the message "Not all Continuum plugins are licensed on this machine and the option to “Remove all unlicensed plugins.” I select that option and click yes, but when I run it again I still get the same option. Is the tool not actually removing the unlicensed plugins as it should? If it is, why do I continually get that message?
