Okay, I tried it again with the other notifications on the 2nd device shut off. (same result) I noticed that if I shut off the 2nd gatttool the notification return back to the first running gatttool.

Yes, confirmed with gatttool. I used 3 terminals with one running btmon and the other 2 gatttool. I started btmon then ran gatttool on one terminal starting the notifications. Then I started another gatttool in another terminal and that new one then showed the results of both devices while the first gatttool stopped displaying any new notifications. You can see in the btmon that the values are coming from 2 different connection handles but the results are all coming through the 2nd gatttool. Here's the outputs using 3 terminals connected to the device (first listing was connected first):
So it's perfectly clear: This all works fine on an x86 machine, but is an issue on ARM
