Under NSM, midi port contains nsm client id, but sometimes not

[grammoboy2]

Using jackd 2 a2jmidid -eu Zyn 3.0.7

Most of the time the midi port of Zyn fusion contains the nsm client id, but sometimes not, which make reconnecting unreliable.

The last one has no nsm id, see below. I've encountered this several times.

I could not replicate this with drumkv1_jack or non-sequencer. jack_lsp:
