I have my source water profile setup in my recipe as "RO Water" (I added this profile if it makes a difference) and "Pilsen (Light Lager)" as the target. When I click brew and go to the Water Chemistry tab the target is correct but source only lists "NEIPA" in the dropdown. NEIPA is also a water profile I added but do not wish to use as a source. The first screenshot I posted is from the recipe page and the second screenshot is from the brew session water chemistry tab.
