See image. The tooltip for the next level of the space station (level 3) shows "2,0 ==> 48 space science". It does not show the Electronics IV required for the research. After upgrading the station, it shows that information in the space station view in the middle (not the tooltip).
The tooltip should probably include the symbol for Electronics IV there right next to the 2,0 as I assume now that the 2,0 is supposed to mean 2,0 Electronics IV.
I gathered all resources needed to supply the space station to finish the fast breeder research (rocket materials, crew supplies, parts for maintenance), upgraded the space station and could not do the research as I had not produced any Electronics IV. Those did not show up as required anywhere.
Edit: version is Update 3 | v0.7.6a (b466)
