Sick pay/pto confusion on check stub

My bf has been at his company for almost a year and it is a very small company (less than 10 employees). His check stubs have never listed how many sick hours he has, according to state law they should be doing so. For a while it also showed vacation hours available as 40, in assuming they just gave him 40 hours as it had never showed anything in the amount earned section. He took a few days off and when he asked if he could use sick time they told him he only had 10 hours because it reset at the beginning of the year. I was under the impression it goes by the anniversary you start working and that if you don't use any it will carry over to the next year, not exceeding 3 days. Then when he asked if he could use PTO they said they don't offer vacation days. On his newest check stub it magically appeared how many sick pay hours he's earned, but where it use to say vacation it no longer says it. Are they wrong or is there anyway to fix it?
