Manual Captions Updated Zoom app, strange!

In ZOOM, before, when I wanted to manually caption, I would assign myself, and I could caption the meeting for ---I could identify who was speaking with typing identifiers. Now, it shows that I'm the only person talking, and it is like one run-on sentence -- I cannot separate different "speakers" -- NOW, it looks like this:

[MC] >> PROFESSOR:  How are you doing today?    >> STUDENT: I am

fine.    >> PROFESSOR: Good, now go to page 457, and we can

[MC] continue with the lesson from last Tuesday.  >> STUDENT: Really?

I thought that, well --    >> PROFESSOR: Well what?  Didn't you get the 

[MC] announcement from the online instructions on the school's website?

BUT IT USED TO LOOK LIKE THIS: 

>> PROFESSOR:  How are you doing today?

>> STUDENT: I am fine. 

>> PROFESSOR: Good, now go to page 457, and we can

continue with the lesson from last Tuesday.

>> STUDENT: Really? I thought that, well -- 

>> PROFESSOR: Well what? Didn't you get the announcement

from the online instructions on the school's website?

Does anyone know how to fix this so it looks like it used to?
