December sitting? – Help!

Good morning all,
I’ve just had a meeting with my Kaplan talent coach (I’m under an apprenticeship). She asked me what my plan was for the rest of my skills exams. I have three more skills exams to take before I take my strategic ones. (PM, FM and FR)

I said to her, I’d like to take FM in September 22, PM in December 22 and FR in March 22.

She seemed to disagree with me, saying that PM and FR I can only take during June and September sessions.
Which throws a spanner in the works for me because… just as everybody else, I’d like to not waste time and get them done as soon as possible.

I immediately went to my ACCA, on the exam planner.
I was able to successfully add FM as an exam just fine for my September sitting. So far so good.

Then, I tried to add PM as my choice for the December sitting. This is the message I got:
“This exam is not available at December 2022 exam session. You can book this exam at September 2022 session.”

MY QUESTION:

Did I get that response because ACCA have not released the December dates yet, OR because the Kaplan talent coach is correct?

I’m panicking really badly right now. Please can someone shed some light? I did not think there would be any restrictions on the sittings!
