Cannot resolve unit name

Hi, thanks for the advice

I am pretty sure that my .bpl files are already nicely consolidated.

My System Path has 17 entries, 8 of which are Embarcadero (I have 10.3 and 10.4 installed)

These are the entries for v10.3 (I think), and the .bpl files for WebGMaps and AdvCharts packages are in these folders:
C:\Program Files (x86)\Embarcadero\Studio\20.0\bin;
C:\Users\Public\Documents\Embarcadero\Studio\20.0\Bpl;
C:\Program Files (x86)\Embarcadero\Studio\20.0\bin64;
C:\Users\Public\Documents\Embarcadero\Studio\20.0\Bpl\Win64;

Does this all look OK?
