Printout Source Credits Duplicated

[PaulStephenson]

I am trying to find where the credits on the "printout" are pulling from in the Basic Viewer app. Source credits, not AGOL credits. I have two different versions of the credits simultaneously displayed in the bottom right; one is displayed with an extra comma (screen-shot attached). I have gone through each service the map consumes to make sure they are all reading exactly the same but I haven't yet found the source. The next step is to see whether these still duplicate on the printout if their sources read exactly the same? I will likely have access to customized applications in the future, but for now I am stuck with the pre-configured apps...

Any input would be appreciated!

Thanks

Paul

Update: I've found that one set pulls from the data, while the other set is pulling from the basemap. There was a custom basemap used in this case, so that is why the credits were essentially duplicating. Changes I had tried making to the credits weren't reflected immediately so I was unable to determine the cause at that time.
