Partition Manager 11 Deletes System Restore Points

Hello,
I have Partition Manager 11. Whenever I save backup partitions C: and D:, both have System Restore points enabled, PM11 deletes the restore points for the D: partition. Is there anyway I can prevent PM11 from doing this? I am using Windows 7 SP1 Pro.

Does Disk Manager Pro 15 delete System Restore points on the D: partition like PM11?

Does Paragon provide tech support on this forum anymore or have they discontinued this service?
