Applicants who want to change their green card application from employment-based to family-based must initiate a request with USCIS. When USCIS receives a request to change an employment-based green card application (for which a visa is not available) to a family-based green card application (for which a visa is available), the Service Center contacts DOS to ask that the pending employment-based visa request be deleted from IVAMS."

From the above, considering one pending visa request per A.No , whenever uscis asks visa number for a porting case, they must delete the already pending request from the system . Eb3 cannot have two AOS(I-485) pending at the same time (1 in E2 & 1 in E3 is not allowed anymore, converting the existing to other basis is encouraged) , whenever there is an addtion to EB2 in the demand data, there must be a deletion in the eb3 total, which is not happening in any of the DD consistantly.
According to Murthy law firm,
"The interfiling request should be based on a priority date that is current, although many such requests are initiated prior to that point. Regardless, no action is taken by the USCIS unless the priority date under the new basis case is current. "
