Showing wrong Virtualization state for VMs with Management agent 9.1.100

[Gnggi]

in XCP-ng Center a virtual machine (Windows) with the new Management agent 9.1.100-59 installed with https://github.com/xcp-ng/win-pv-drivers/releases is showing "Management Agent not installed" on VM General Properties Page.
In XEN-Orchestra "Management agent 9.1.100-59 detected" is diplayed.

Same issue. Adding some additional context and screenshots.

Both versions of XCP-ng Center are returning a Management Agent not installed error under the Used Memory column when using the 9.1 driver (this was also an issue with the previous 9.0 version).

Although, XOA does show that it's installed.
