I am currently working on NIFI-12960
<https://issues.apache.org/jira/browse/NIFI-12960> where I added a new
property named password which allows a user to enter a password for reading
a password protected Excel spreadsheet. I marked this new property as
sensitive. While testing I entered a password and now in the UI it says by
that property "Sensitive value set". Is there a way to unset this property
to allow for adding a different password? I have tried checking the box
"Set Empty String" but that does not clear the "Sensitive value set"
message.
