This question was asked and answered by the US embassy in an article in the Jamaica Observer – You are allowed to have multiple visas:
Multiple non-immigrant visas are routinely issued at the Embassy –
common combinations include the B1/B2 visitor’s visa in addition to
crew member (C1/D), student (F, M), employment-based (J, H) and
performer (O, P) visa categories. As long as you still need multiple
visas, and they are valid, your visa will not be cancelled when you
apply for a visa in a different category.
This appears to fit your situation.
