XenCenter doesn't allow more than 7 Storage-Devices on Windows

Though https://docs.citrix.com/content/dam/docs/en-us/xenserver/xenserver-7-0/downloads/xenserver-7-0-config-limits.pdf says VM Limits are 255 VDIs per VM and AFAIK Windows VMs should support at least 15 VDIs, I can't add more than 7 (+ the mandatory "DVD Drive 1").

Of course XenTools are installed. Xen Center 7.0 and 7.1 are affected - didn't test 7.2 (is it even fine to use 7.2 with XenServer 7.0? I remember that there have been problems with combination of newer XC and older XS).
