Hello elsismologo54, and welcome back to the community.
Thank you for the description of the issue and all the screenshots you have provided (great vault installation!)
Could I please ask you to download the logs from the Shake and send them to me? If needed, instructions on how to do it are here: Please read before posting! We can try to take a look and see what could be causing this issue.
Also, could you zoom in on one of the larger spikes in SWARM so that we can see how the waveform is structured?
Thank you for your collaboration.
