Bizarre words and acronyms in dictionary, can't blacklist them

[RedDust99]

I imagine I'm doing something wrong here, but I purchased the Futo keyboard app a few months ago and it's running dictionary English v1, Filename ml4_1_f16_meta_fixed.gguf I fight to get the word and because this thing fills in things like ACD ACS. I should mention that I use the swype method, but even if I end up having to give up and manually type in a word, the offers of what I might be looking for are bizarre. Some are complete jibberish. When I try to blacklist, nothing happens. For example, just is almost always Judy. I try blacklisting it and it just sits there in the alternatives and I cannot get rid of it. Sometimes if I blacklist something twice then it disappears from the suggested area, only to reappear again.

I'm a noob, is there some way to manually edit this dictionary? Do I have the wrong dictionary somehow since it's loaded with capitalized and other words and acronyms I'll never use? Thanks for any pointers in what I've somehow missed trying to read through and understand why using this keyboard alternative is such a fight for me.
