AE 24.5 Roto brush keeps propagating
Hi,
I'm quite new to AE.
I apologise in advance as I'm not familiar with all the terminology as yet, although very familiar with PS/LR and Apple media programs.
I have taken a couple of AE beginners courses and all went well. I'm making my own project and have used the Roto brush. The first time it worked easily, I was able to make a video that is about a minute long and sucessfully export it via Media Encoder. However, I wasn't happy with it so I tried to re-do the Rotobrush part of the project which I wanted to export and then add into the original project as a finished .mp4. However, I cannot get AE to stop propagating, even though I havn't added any further refinements after the first frame. I took a chance and I did try to export it, it started well but then stopped.
I've spoken to Abobe support who checked my system and said it's sufficient and should run the program (they sent me a tutorial but it was the same info as the one I'd watched on th Adobe site ) I then I spoke to Apple who checked that all was well with my Mac. I understand that my processor should be better but Adobe support didn't seem concerned.
Can anyone help me please?

I have all of my media on an external 4TB HD and another 1TB one just for the cache.
Many Thanks
