BLS Spain online form generated wrong details on the PDF

Has anyone else had issues with the BLS Spain portal auto-populating incorrect information onto the final PDF application form? In my case, a few answers ended up in the wrong fields (like hotel details appearing in the box asking who filled out the form), even though I filled in the online portal properly.

I emailed BLS support asking how to get this corrected, but they just sent back a generic template response telling me to download a form from their website and fill it in electronically, but didn't clarify if it means redoing the application on their online portal or me personally typing the answers in on a blank form.

If you had a similar glitch, how did you fix it for your appointment? Did you download a fresh blank PDF and type over it using Adobe text boxes, fill out a fresh blank form by hand with a pen, or just cross out and correct the errors manually on the printed portal form? Any advice from recent experience would be a massive help!
