Am I under level? At blue greymon boss fight

Digimon are level 13. It didnt beat me or anything. Just failed to stop its charge up attack. Makes me wonder if my team is somehow behind.

I did a lot of random battles. I had type advantage. Dont think ive missed a side quest, so all digimon are still rookies.

Im not actually worried. Just sorta more like "wow I didnt stop it in time!" When on balanced difficulty lol.
