I don't know why this was happening but for information purposes I have solved the problem.
By opening each of the 7 + custom settings and using the Q button I was able to save the MF Assist setting to "Peak" for each one. The setting now remains permanent.
Thanks to everybody who tried to assist.

I recently got this used camera from eBay. when I first got it the flash was working just fine. I would pop it and it'd be on auto and it would work. Now I can't seem to get it to work. I pop the thingy on the side and this icon pops up saying that flash is off. So I go to the settings (I've tried this with every mode on the wheel spin thing) and I go to the menu section where I can choose flash settings but it's non accessible. It only lets me change the Red eye removal setting. What's going on? Do I need to update the firmware? Did I get a faulty camera?
Have you considered the many 150mm - 600mm options?
Fujifilm offers one that does work with both the 1.4x and 2x tc.
If you want one that has brighter f-stops, then Tamron and Sigma offer them in various mounts. You can pair them with oh, say a Fringer smart adapter (or one of Fringer’s competitor’s smart adapters) and get aperture dial control as well as having correct EXIF stored in the images. There are plenty of reports these adapters work with teleconverters, I suppose you can write the adapter’s manufacturer and ask if it matters if you use camera -> xf tc -> adapter -> lens or camera -> adapter -> native lens tc -> lens.
Depending on the budget, you may be able to find a setup in the new or used market you like.
