Error when removing some ESRI basemaps from the basemapGallery

I am using the ArcGIS JS API 3.16 and I am attempting to remove some of the ESRI basemaps from the basemapGallery.  Some of the items are being removed, but I am encountering an issue with the last item not being removed (when the index gets to 10).  The error is 

 

"esri.dijit.BasemapGallery: could not find group for basemaps.".

 

Any ideas?

 

The code is attached/below.

 

Thanks...Chris
