What version of BLHELI_S is installed on these ESCs?
To be honest I am not sure off hand, since our latest batch only arrived about a week or so ago I imagine they have a very recent version on it.
Use BLHeli Suite on your PC to read the data in the ESC,
If you are not familiar with this method there’s loads of stuff on YouTube.
If you have a modern FC you should be able to connect to the ESC with that instead of using a separate USB Linker
Hope this helps
