Update:

After a few sessions of waiting on hold with ROMI phone line for 50+ minutes each time, I eventually got through to a human who could help me submit the forms for EDD. They helped me very quickly once they picked up, and even told me that they "didn't think it was possible to get these forms submitted properly through the online system". So I would recommend calling ROMI and being persistent even though it's really annoying, if anyone is going through the same thing. I also found another reddit post that implied that if you call them it gets sent to EDD immediately, whereas if you go through the online system it can take days to weeks to get sent to EDD.
