A new WMS layer is not visible in GIS0030 form after it was created in Map Builder. Everything seems ok in Map Builder – a new WMS layer is visible there.
There is a bug in Map Builder that means the “Duplicate” functionality does not work correctly for WMS Themes,
please do not use this option to create a new WMS Theme as it will not be visible to the GIS0030 form so will not be displayed in Exor Locator map.
