I just played a hand where two of us had full houses, eights full of seven. Per the log, my kicker card was an ace of clubs. The other player's kicker was a seven of clubs. It seems to me, I should win.

This is what the log has for the outcome of this game:
"Human Player shows [A♣,7♥] - "Full House, Eights full of Sevens"
Player 3 shows [5♥,7♣] - "Full House, Eights full of Sevens"
Human Player wins $25020 (side pot)
Player 3 wins $4910"

Could someone explain how this is correct?

There is no kicker when you both have the same full house. A hand is always formed of 5 cards. A 6th card will not count.

In this hand "Human Player " had more chips before this hand. If you are the short stack, you cannot win more chips from other players than you put into the pot. And it was a tie anyway as you had the same hand.
