Thank you for sharing the outputs. I see that this sharing group is a part of multiple VLANs, are you seeing a similar output of this port in all the associated VLANs?
Can you please also share the following output from all the sharing group ports?
debug vlan show vpifs PTP_rt1_msk-rt7_msk
Can you please also share the following output from all the sharing group ports?
debug vlan show vpifs PTP_rt1_msk-rt7_msk

Hi,
From what I recall of some past labs I did, it can happen to have both. If I remember correctly, this can be due to another protocol disabling the port. I'd try to see around ELRP, MLAG, EAPS, Port Mirroring... see if there's something relevant in your context/config.
Why is 45 the current Master of your LAG while 46 is the configured Master?

It is expected to see the less active port number as the current master irrespective of the configured master. That mystery is solved. 

If the port is blocked it will typically have a "b" next to it not a "!". Can you try to toggle the port on and off to see if the flag resets?
