Some snippets don't work like expected

Issues

First of all, the mk snippet doesn't show up for some reason.

This is another small irritation I have, the date is more important than displaymath.

Then the matrix snippet shows up.

However, when I add dimensions it doesnt work anymore..

The mk snippet is an autosnippet, so by default it isn't included in LSP.

The other two issues likely lie in using friendly-snippets or maybe LSP snippets for LaTeX. I don't have a date snippet and matrix snippet from this plugin is a regex snippet so it shouldn't show up on LSP.
