LACP works on one trunk but not the other?

I have a HP 2530-48G network switch that I use in the lab. I have 2x Synology NAS, both with Dual-Nics. I am trying to get them both LACP bonded to the switch (on seperate trunks) but am having problems I believe with the 2530-48G.

NAS1 - Trk1
Ports 45 + 46

NAS2 - Trk10
Ports 41 + 42

At this time, I can connect fine to NAS1 on it's bonded interface. However, I cannot connect to NAS2 on it's bonded interface. If I switch the cables round so that NAS2 is plugged into 45 + 46, I am able to connect to it immediately, which leads me back to the 2530-48G and it's configuration.

If I CLI into the switch and run

show LACP

Select allOpen in new window

I get the following output

LABCORESW(config)# show lacp

Nothing seems to be untoward. Any ideas?
