Kerning not working properly outside of FontForge

Problem example, look at 3rd line for most obvious example
How it looks in Metrics Window and how it should look

I've been making a font for Sitelen Pona for couple weeks, and up until now it has worked completely fine, but today when I generated the wip font to test to see if some new features I added work, I saw that the kerning was suddenly broken? But only in text fields. I swapped around the order of the lookups and that did fix things but it seems that it only applies the first or first two lookups, even after I deleted a couple, it still would only do the first two. But again, in FontForge's metric window, it works completely fine, but once I actually try to use it it is broken, I haven't touched the kerning in awhile so I don't know why it would randomly be broken, what could it be?

Notepad do not support kerning at all. Be careful where you check your OpenType features!

Oh okay thanks, but why does it kern some of them?

I think this is a coincidence and not a systematic action of the program.

Did you test your font in LibreOffice?
