Different Allocated sizes of TPVV between Main & DR HP 3PAR Storages

I have noticed that two members of Remote Group of HP 3PAR 7200; one at Main Site and the other at DR site have different allocated sizes. At each site the TPVV size is 500GiB, but allocated size is 182GiB at Main Site while it is 1.75GiB at DR site.

Note that RC is synced and I suppose that two TPVVs are synchronized and have same data.
Please anyone can explain and advise . . .

Do both volumes have Zero Detect on? Are you using an asynchronous periodic group? How often does it resync?

Thank you Smith. 

Yes all TPVV have Zero Detect Enabled using Async periodic group.

Resync is Auto.
