Does this mean I have no compression in one cylinder?

I would say "Yes". You have 7 humps and a space for the 8th. The hump, after the space, is a bit higher than the rest, which is to be expected.

Now, throw a sync on an ignition event, and number the humps/cylinders in accordance with the firing order.

My apologies. I just realized that you are using the Uscope, which is single channel.

Bad news on the engine :-(
But you made good use of the uScope that is a really good capture it shows all the classic characteristics to look for.
