App Designer - Find In... not finding text

Using PT8.55.13 on MSSQL

Trying to find where in an App Engine the message being produced.

I click Edit > Find In... and set text to be "17005, 2032" (without quotes).  I then choose to only search App Engine PeopleCode.  The search results return zero results.

To prove this is an issue, I copied a message number similar to the above from an App Engine, and pasted directly into the text.  This again produced zero results (even though I had it open on the screen).

I have tried searching both community and support for known issues, but of course the words "find" and "in" are commonly used, so the search results weren't relevant.
