So for some reason, Presto Music thinks it's a great idea to have the year field look like: 2023-02-23\\1987. How do I just display the year as 1987? The rest can be deleted. I tried regular expressions to no avail.

It looks like a multi-value field - which you can check in the extended tags dialogue which should show 2 fields of the type YEAR, one with `2023-02-23` and one with `1987`.
You can now either [remove all duplicate fields](https://docs.mp3tag.de/actions/remove-duplicate-fields/)
or [merge the duplicate fields](https://docs.mp3tag.de/actions/merge-duplicate-fields/)
or if you want to get rid specifically of the first piece of data then try an action of the type "Guess value"
Source string: `$meta_sep(year,==)`
Guessing format string: `%dummy%==%year%`
