Lathe Post thread milling feed rate issue.

I have noticed something unusual while running some milling toolpath on my Smart Machine Tool NL2000M CNC Lathe.

(Live tooling no Y axis). While contouring the feed rate is outputting normally but while trying to run any inside toolpath like boring with a milling tool and thread milling the feed rate while running in incredibly slow. I'm still learning Lathe G-code so I'm not sure what to change either in the post itself or something in Fusion 360 I can change to correct this issue. I am attaching both the posted code and the Fusion file for reference. Outside milling is normal "inside" Milling runs way too slow. (boring/ threadmilling ops) 

 

Note: this file is just an example file to show what I mean not and actual part. I'm just trying to figure out how correct the issue for future parts.
