Now that I have the TOS 6 Beta installed and working, the only issue I am having is creating the HyperCache. I installed the NVME drives in my PC and did a Diskpart Clean to erase them before I installed them into the Terramaster NAS, but I don't think that is the issue as I have no problem detecting them in TOS 6, and I can even set them up as a storage pool 2. Plan on waiting for the next TOS 6 update to see if that will fix it.
It should be easier to create/delete SSD cache on TOS 6.
Regarding the issue you have encountered, we suggest that you contact the customer service window on the official website or technical support email to make an appointment for remote troubleshooting.

I've contacted the support team and we've scheduled a remote session last Friday in the window suitable for the Terrmaster engineers but nobody came and also nobody is answering to my mails. The problem is still there.
As a customer I never had an experience like this before. You've to improve a lot in customer caring Terramaster.
