Text becoming unattached

I’m applying text to the faces of objects within the studio. In this case, making little tags to label trees.

It has usually worked well, but in my most recent run the text is somehow unattaching itself from the face of the tag, and creating air space under the text. The slicer complains because the text needs support. If I enable support, it makes an undesirable arrangement of support between the letters and the face of the tag.

All of this has seemed to happen automatically. So far I have tried repairing the model, vertically scaling up in the z axis only, and neither of those seems to fix it.

I printed a batch anyway, without support. Some of the letters are adhered sufficiently, some not, but the whole situation is definitely sub-optimal.

The only solution I have left is to remake 50 or so tags with 2-3 text objects per tag, but honestly I don’t want to invest an hour if tedium if the problem is just going to re-emerge.

Has anyone encountered this? Any ideas to try and fix it?
