DSLR suddenly switches from RAW to FINE

I’ve noticed that sometimes my Nikon D3400 suddenly “decides” to switch from RAW to FINE (most of the times it happens when I take the SD card out, but I don’t really understand why). Is there anything I can do to fix this issue?
Honestly it’s a bit annoying having to check every time that the file format is the right one.

My camera is in manual mode 99% of the times, but I have just set RAW and made a slow switch to every mode and the format didn’t change, so I don’t think that the problem is scene or automatic modes defaulting to FINE.
