Space Engineers (XBOX Series X) , unable to attach small grid blocks to a connected small hinge head

Dear Sir/ Madam,

I would like to build a "custom ball turret" within Space Engineers ( XBOX Series X ; after Hotfix 1.206.032 ). With the old technique it never has been a problem; after the option to directly connect a small hinge head to a big hinge base, it doesn't work ?!

I will describe step by step my workflow.

Step1: I start with a big grid conveyor as base for the custom ball turret.

Step 2: On top of the conveyor I place an advanced rotor.

Step 3: On top of the advanced rotor I place a hinge (5x5).

Step 4: I delete the big hinge head.

Step 5: I place a control seat next to the construction.

Step 6: I jump into the control seat and open the control panel.

Step 7: I select the hinge 5x5 and attach a small hinge head.

Step 8: I check that the small hinge head is visually connected and functional ( small hinge head can be rotated by 180° )!

Well, all seems to be fine!

But now I run into trouble!

Step 9: I try to place more small grid blocks ...

- I have to place small grid conveyor blocks; connected to the small hinge head.

And exactly at this step I run into trouble!

The game logic doesn't give me the option to connect small grid blocks to the small hinge head.

my workflow: I press the left stick to open the building menu; I select a conveyor and confirm with RB. All I will get is a big grid block. I tried to change the size of the blocks with LB+X, but I still just get a big grid block. I changed the size of the blocks with LB+X in the building menu to small; but again I just get a big grid block.

With one word: " I cannot attach small grids to my small hinge head."

- not the desired small grid conveyor, nor weapon blocks!

I attach a screenshot of my construction with the correctly attached small hinge head.

I am doing something wrong, or is there a bug in the XBOX game version ?

I really hope you can give me a helping hand how to select and attach small grid blocks to my small hinge head ...

Waiting for your answer...

Best Regards

Mr. Fischer
