Cura 5.3 Stable release Support settings bug.

[jlspeeddragon 3]

Using Calibration cube rescaled to the following (Dims: X28 x Y28 x Z 4)

Moved block up 4mm Z. (had drop to floor option unchecked).

Duplicated Block, Centered so that they were stacked center, one stacked on top of other.

Assigned bottom Block as Support (as seen in reference Picture).

Supports Turned on Using Normal: Touching Buildplate, (same problem with Everywhere setting, and Tree).

Sliced Model.

Cura did not assign the bottom block nor show in preview mode as supports, instead dropped it to the floor and voided out the top block.

It should have sliced the bottom block as supports.

I duplicated the same issue on my 2nd PC (HP Laptop with same profile settings etc...) Had the same result.

project file attached as well.

Back to using 5.2 alpha for now, at least until the support bug is resolved.

You can work around this by turning off the "Remove empty first layers" setting. Unfortunately this is not visible when you have turned on supports or there is a "print as support" mesh in the scene.
