Line EFF not reflecting correct value

Hi Team,

We have created a EFF named "WMS Status" at order line level which gets updated based on current status in WMS.

The value on the Line EFF is not reflecting correctly for below case.

ORDER PACKED IN WMS -- DFF Status updated in Fusion
when unpacked/modified OBLPN in WMS, new order line appeared in WMS with cancelled and Created status.

In fusion the line in awaiting shipping with "WMS status" in cancelled value.
when we refresh the order in OM, the "WMS status" changes to Created from Cancelled.

Why the correct value "Created is not reflecting in the EFF at first place"?
