CA - vacation hours unevenly distributed to staff, what now?

Location: SF Bay Area, California

We are not the tightest run ship.

There are less than 10 people employed at the business I'm at. There is no union, and no HR that I'm aware of.

Errors in vacation distribution were found such as someone with half as much time in as me had double the amount of vacation, in addition to other irregularities.

Can vacation be taken away from the people that got more in an error?

I do know that vacation time counts as wages in California.

I don't want to put the burden alone on my manager to push for accountability, I'd like to offer them information on what to tell the owner/ask for.

Thank you in advance.
