This usually means you have an invisible character that PS can't recognize. I did check your PSD and all the layers with problems were 7, 7 copy, 7 copy[n]
so you probably had an invisible character in your layer name, then when you copied it, you reproduced the problem in each layer.
I tried copying your layer 5
instead, and it worked just fine, which is evidence of a problem in that layer named 7 . I'm not providing the PSD because I'm not sure if it rendered the same (for example, I don't have your linked assets), but just do as I said and it will work.
Additionally, Photoshop uses to have issues when rendering to PDF, so a quick trick to make sure you get the same look is to create a layer by using ctrl+shift+C
and then ctrl+v
. This will copy/paste what you see in your document, so PDF will look the same. And of course, you keep editability of document
