Re-check all your hose connections and then, as stated above, re-do the compression test.

Do a dry test first and then do a wet test.

If the compression stays low from both the dry and wet test, could be a valve issue ( valves, valve seals, etc. ) or a ring/piston issue

If the compression improves when doing the wet test, then probably a ring/piston issue.
