Mine came with two tubes.
It did the twist, big time. I decided to move it a little so it rests against the wall. While doing so, I found that every aspect of the two legs was uneven except height.
Closer to one bench by over an inch.
Off center on the table, bench to bench side.
Off center and uneven from the wall to the aisle.
I was hoping to move just one leg but had to remove both.
I carefully centered both leg sockets on the table, spacing them evenly and allowing better foot room while trying reuse or cover any previous mounting holes.
Then I put the leg tubes in place on the table and put the leg floor sockets on the tubes.
I set the table upright. I pushed the table against the wall and carefully measured the position of the floor sockets to keep them even with the top ones from the wall and evenly spaced from the benched. I rotated them on the floor to try to reuse any existing holes. I drilled the new holes as needed and siliconed the unused old holes shut.
My table no longer twists.
I learned on my boat that had a single tube supported table that if the tube sockets allow the tube to tilt any, you can add paper as a shim, like a matchbook cover.
