DPM on Server 2012R2 says that the limit is still 1700GB

I'm Running DPM 2012 R2, UR7 on Server 2012R2, with Azure Backup Client version 2.0.9022.0 but I am still getting the error that the size limit is 1700GB.

127C	21DC	01/06	01:09:50.305	22	vdshelper.cpp(2926)	[000000001C099950]	C81CC131-C747-477A-B3E7-1D1BABC69342	WARNING	Parameter: [0x8004240f], MaxSupportedSize = 1700

This post suggests that the limit should be much higher than that: https://azure.microsoft.com/en-us/blog/azure-backup-enables-backup-of-large-volumes-vms-databases-and-more/

Any suggestions for how I can get the size limit to be correct?
