Kerbal inventory volume is tiny compared to objects

[Kspguy88]

Pretty new to KSP and I wanted to be able to add items onto space crafts that I already has in orbit. I downloaded KIS and KAS to do this. Unfortunately my kerbal cannot hold anything in his inventory because his inventory volume is 1 L and every object is huge compared to that. Is this because he is a level 1? I tried looking through the save files to increase his inventory size but all I saw was max inventory which didn't fix the problem. I have read the user guide and looked all over the Internet and these forums for more information but I can't find anything. Everything is up to date. Other mods are Mechjeb, alarm clock, kerbal engineer and planetshine. Thanks in advance.

I feel for this before. There are controls to do this. This is not a mod problem just read the KIS instruction manual or read instruction videos. Once you read the guide or watch the videos it will become easy

KIS Guide 

Just scroll down to the part that says User Guide(PDF)

Kerbals can move things from one place to another, but it is usually impractical due to awkwardness of moving large masses.

I figured it out... I was installing my mods under the squad folder and not under the gamedata folder. Reinstalled everything and it works fine now.
