What the heck is going on with my chart?!

I had a trigger shot on 9/5 and <a href="https://glowing.com/glow-fertility-program">IUI</a> on 9/6.  Why is GLOW saying I ovulated 9/16?  This is not possible.  I've also never had such a profound temp drop as I had today.  Very hopeful it's an implantation dip but is probably very unlikely because I am 12 DPO in my calculations.
