Welcome @Jeff

Very odd. You do not have a chromosome location for those observations either. Do you want to share the run so we can provide feedback about how to correct this? See → [How to get faster help with your question](https://help.galaxyproject.org/t/how-to-get-faster-help-with-your-question/11469)

Or, you can try a few simple fixes to learn if those are the problem. The most obvious is the presence of # header lines in GTF files from GENCODE. You can remove those headers to see what happens first, then come back here if it wasn’t enough.

Let’s start there, thanks! 🙂
