Switch A works on Bank 6 but not on Bank 2

I'm using the editor to create some Program Changes on my Eventide H9.

There's a moment when a switch stop working and doesn't send midi anymore. I've changed, name of preset, another value un PC, toggle on or off, bling on or off,... everything... but the switch doesn't send midi anymore. So next step i tried is to go to another bank and start again to see what happen. Configure a PC on switch A, and works well, star to make some changes on that switch, and theres a moment when stop working.... The last thing i tried is to make a new one on bank 6 and all switches worked fine... so i copy the whole bank via preset manager software and paste it on bank 2... and.... switch A isn't working again.... but on bank 6 it works correctly. So i don't know what is happening with this. its like its bugged and keeps in memory for some reason that this switch don't work again. But the switch is correctly doing his work because i can press A+B and do the bank down, and works ok on other banks. Its happen to me on other switches too (this is an example to show you this strange issue)

Thanks.
