Header Project flashing random colours

Header Project flashing random colours

Hello,
I am using Zenon 6.20 and normally if we have a pc fail onsite because we have them all raided we can swap out a harddrive, change its credentials and we can recovery fairly quickly. However the siemens box pcs that we use has gone from a IPC627B to a IPC627C so we cannot use a raid from the older B series.
I had this issue so had to rebuild a new c series pc with Zenon 6.20 on it and i remotely transported the header / roof project with the sub projects over to it and started the runtime.
Zenon run time boots up fine and you can select the sub projects and control various items, but the header project that displays all the sub projects has an issue where all the sub projects flash random colours like it is scrolling. It maybe red with ES in it , then after 10 seconds purple with RC-A and then yellow etc.
Has anyone got any ideas on this please?
Many Thanks
