Ok so i went to my Britbox channel on Prime and hovered over a bunch of stuff to find things from those decades. I had tried Black Adder and The IT Crowd but they didn't have both resolutions. I finally found Are You Being Served: Again! and that one had both.
I can confirm this is a StreamFab bug as the competitor gets the 720x576 when i select that.
I invite you to create an issue on the bug tracker in my signature

Hi jpp72. Thank you for being so helpful.
An example series on Amazon Prime UK is 'Men Behaving Badly' from the early to mid 1990's. This had both resolution options. If I try to download at the preferred 720x576 I don't get it. I end up with 768x576. File size is less and poorer quality. Surely a bug? It's been fine until the last month or so and Streamfab support are not helping with my support ticket. The nameless support person did not seem interested in helping a paying subscriber to DVDfab365 annual subscription. Shocking really.
Hopefully a different support person will help from now onwards.
Interesting that you have Britbox and I'm very grateful that you've tried helping me by looking for relevant affected tv series that have both of the resolutions previously mentioned. I really appreciate it. I see you found an example; 'Are You Being Served Again'.
I will try your bug tracker and once again thank you very much jpp72
