Unit Production - What do these numbers mean..!?

[endolex]

Hi everyone, I've been wracking my brain trying to understand what these numbers (see screenshot, framed in red) are - there's no mouseover / tooltip info or anything, and all my guesses about what they could indicate (produce several units at once? XP Rank?) turned out to be duds. Help please!

New mods you haven't looked at yet

omg, thanks for the hint - but it doesn't seem to work exactly as intended, as it always shows me the total number of available mods whenever there's a new one, regardless of which ones I've already been using in other templates?

 

[TibblesTheCat]

its new ones for that unit, once you check them out on that unit the number disappears

Yeah, that seems to be the intent - though I think it's buggy. It shows me the same total number of 7 available mods, regardless whether it's a standard version or already modified template...(see below)
Anyway, thank you for explaining the function!
