@macidev yes - I had similar issues on 6.2 RC .. but on the properties edit page (/admin#/sw/property/detail/UUID). (so editing of the property itself, not on the product page). On that page, only the first 10 are shown and you will need to use the search-box the find others.
I did not check the product page yet, but I suspect these issues are related

Can anybody help me with creating orders through the API. These are old orders I am importing. I post to the /order endpoint.

I post them in the same call - but for both I get this error:
This field is write-protected. (Got: "crud" scope and "system" is required)"
