Why did RH auto sell my LEAP and buy the CC that I sold that was going to expire worthless??

I’m pretty pissed rn because not only did I not want to sell this LEAP, but Robinhood sold it for such a shitty price! And it made me buy a useless call that expired 5 fucking minutes later!!! Why wouldn’t it let the call option I sold expire worthless, and do nothing to my LEAP? I bought/sold these calls on completely different days as well
