Query: Doesn't fit regular faucet

I bought a new Moen faucet and tried to attach this filtration system. The system came with two attachments for the internal attachment of the faucet. Both were the same size but different colors, and neither of them actually fit the faucet. They were both too small. I didn't have this problem with other systems, so this one must only work for people who have external attachments.
