After setting GWEI Metamask speed up doesn't work

I have been setting GWEI for minting my pieces, but when I decide to speed it up, and I press submit in Metamask, it doesn’t push it through, it keeps it hanging on the old GWEI set. Any advice?

On a side not, when I try to add hashtags to my posts, it only let me choose 5 options and usually the subject I am asking about is not in this list?
