So here is how I have broken down the information.
Crew and ships complement are never used together or is either one or the other.
Crew is used to reference planetary vehicles and ships compliment is used for space vehicles. Both refer to the amount of people it can hold.
Starfighter Compliment is what type of space vehicles are stored on it.
Vehicle Compliment is what type of planetary vehicles are stored on it.
A good chunk of capital ships have all 3 categories seperate, such as the Imperial I-Class Star Destroyer on page 281 of the Age of Rebellion Core Rulebook. From the books they seperate all 3 categories.
I suppose you could rename starfighter comp to Starfighter/Vehicle comp and just combinde the 2 entries into one big one.
If you were to add both categories seperate, they there if you want them and if you don't, It doesn't show up saving space.
Still I will leave it up to you.:)
