When using the font SF Pro in bold it becomes a different variant, how to fix?

[Karin31926950797b]

When I use Apples developer font SF Pro in photoshop in Bold it turns into a cursive version, even when I try to change it back. In the weight box, it changes from Bold to Optical Size YAXS Weight-700 How do I fix this? It's basically impossible to use the bold version now.

Update: It's only in this specific PSD file that this happens.

Something about that specific PSD, Karin?

Have you tried copying the file at the OS level? (an old trick that works .0001% of the time)

Have you tried copying the text into a new PSD?

I don't see cursive (handwritten). Italicized?

Not a solution, but I have the exact same problem. The PSD file has 45 layers and started acting up around 40 layers. Initially, the four text layers with SF Pro Bold were OK, but when I started adding new layers, it got weird and converted four SF Pro Bold text layers to "Optical Size YAXS Weight-700". I replaced SF Pro Bold with Roboto, since the PSD file is for making YouTube miniatures, but I would prefer SF Pro Bold...
