multiple e1with slip seconds

I have two cisco routers both with  VWIC-2MFT-E1 and they are connected by 2 x E1 circuits with the same provider.

I have multlink created to bundle them together, i am seeing slipped seconds on my e1 link 0/1/1:0

Is there anything wrong with my config, or what should the correct config be

Router A

network-clock-select 1 E1 0/1/0

controller E1 0/1/1
 framing NO-CRC4
