When parsing GTF files, the start location is decremented twice rather than once to correct for 0-based indexing

What steps will reproduce the problem?
1. Parse any GTF file
2. Compare gtf-to-genes start locations to GTF file
3.

What is the expected output? What do you see instead?
Start locations in gtf-to-genes should be 1 smaller than in GTF file, but they 
are 2 smaller.

What version of the product are you using? On what operating system?

Please provide any additional information below.
