Let go from semester internship

I was let go just about a month into my fall internship at a boutique in the financial services industry (was supposed to run a bit into spring semester) because my interviews kept falling on my work days and I had to ask to leave early/come later to make the interviews and was told my schedule will not work with the firm and that we should end it here.

I have an offer and one more superday coming up. How is this going to affect me in terms of BG checks? How should I go about disclosing this information? I was told prior to signing with them that they would be very accommodating for academic obligations – I never asked for academic accommodations, only a couple hours here and there for these past couple weeks for interviews, but I understand how that could come across. I'm really upset because I tried to make it work, offering extra hours on the same or other days to make up for the lost hours, and reassured that recruiting would end soon, but as soon as I said I had an offer lined up for the summer they let me go. Now I'm concerned about how it may affect my current/potential offers. All help will be appreciated.
