What does this "6x" mean for wrap logic in Dev Mode?

Hi friends! I have a quick question:
When inspecting in dev mode, I noticed a gap value displayed as “6x” with an info icon. This container is set to wrap, and the actual gap size is 24px.

Do you guys know what the meaning of “6x” in this context? And how could I expand the info icon to learn more?

Thanks in advance! 🙂
