[Yeast] Problem with -His plates

I'm new to working with yeast and I've got trouble with my -His plates:
I've prepared to batches of -His plates using batches of CSM-His from
two different labs and adding glucose (Fisher Scientific), N-base
(ForMedium) and bacto-agar (BD). I've plated His- strains (which are
definitely OK) on these plates and they grow on both batches of plates.
I restreaked the yeast to the -His plates to make sure they don't carry
over too much His from the YPD they were grown in but they still grow
when restreaked on -His plates.
Has anybody ever experienced problems with His contamination of glucose,
N-base or bacto-agar?
Thank you for your help.
