GFF3 feature too long in IGV

Question

[ajaymaran97]

I created my own gff3 file that has CDS, UTR, and exon annotations. When I load the file on IGV I can see certain sequences are covering the entire chromosome. However, when I check the gff3 file I don't find any transcript that is that long.

Here's the view from IGV

This feels like a messed up annotation where the chromosome is tagged as the parent of many exons or something similar. GFF is a hierarchical format where the parents of features on different lines are tagged in the Parent attribute.
