Custom URL Parameters not updating properly

[Chris D]

I believe there is a bug for updating and removing Custom URL Parameters
When I try to update url parameters for adgroups through the UI we receive errors.
When I try to update url parameters for adgroups through the api I see that the previous 3 parameters still exists in the list but are mark as remove.
However when attempting to save it is throwing error

idError.NOT_FOUND @ operations[0].operand.urlCustomParameters.parameters[3].key; trigger:'nameOfParameter'

Hi Chris, 

Could you please enable logging and share the complete SOAP logs when you try to save the custom parameter via API? Also, what error were you getting while attempting to update that from the UI? Could you also share a screenshot of the UI error? Please use reply privately to author while sharing the logs and the screenshots. 

Thanks,
