CRM onpremise to CRMOnline - unable to create activityparties for custom activities

I have been searching for an answer to this over the last week to no avail.

I have created the custom activities without issue, but when I try to add the custom parties to these, I am getting errors relating to the fact that the ACTIVITYTYPECODE is only showing the OOTB activitytypes.  I have taken efforts to remap the source activitytypecodes to the new values already.

I read about modifying the metadata and attempted this with no success.

If anyone has any suggestions, please advise.  ​
