Ortlieb Quick Rack XL – play in rod adapter normal?

Just installed a new Quick Rack XL with the Ortlieb thru-axle.

Noticed quite a bit of side-to-side play in the rod adapter where it attaches to the rack (the pivot on the rack itself). When the rack is attached there is still a bit of movement, which I assume could cause some wobble or noise when loaded.

Everything was tightened according to the manual.

Has anyone else experienced this with the Quick Rack, or is that joint supposed to be tight with no lateral play?
