Enhancing a reactor with either Heliotrope fuel or at the Arcology School of Engineering results in an enhanced reactor but no '+enhanced' tag shows in the dock service screen <Controls> ItemDisplay.
A '+enhanced' tag is also missing in itempicker lists. See image, one reactor is enhanced and the other is standard.
The enhancement works, reactor power and price are both increased.
