Compile with warnings after editing browse sequence

I compiled a help project today and received multiple warnings.  One of the warnings indicated my browse sequence file was external and would not be copied to the output folder.  I generate three other versions of the project using conditional build tags.  I tried each of them, and all of them still worked as expected.  As part of my troubleshooting process, I restored the browse sequence for the version of the project on which I was getting the warnings.  The project generated without warnings.  I deleted one topic from the browse sequence and added one topic to the browse sequence using the UI.  When I generated the project, I again recieved multiple warnings.  I examined the .brs file in NotePad++. The system had copied the first topic in the browse sequence (the welcome topic) to the end of the browse sequence, duplicating the topic in the browse sequence, and did not put a line separator between that topic and the closing browse sequence tag.  I edited the browse sequnce file in NotePad++, and the project now compiles again without error.  Anyone else run into anything like this?  Thanks! For reference, I am using app version RH 2020.8.34, on Windows 10, and generating frameless output.
