Veeam email alert all restore points deleted because of disk space increase

I have Veeam backup and recovery and was wondering why I received the email message after I added disk space to one of my VM's using VMWARE.  I added 50 GB and then rescanned the drive and increased the drive space.  Does it always delete all restore points when you do this?  I thought I've increased disk space before in VMWARE and did not see this message.
