I'm new to creating templates, so please forgive me if I'm struggling a bit. I managed to create the infobox easily, but when I try to insert my template into other articles, it displays incorrectly, resembling the appearance of a page's headings or something similar (as shown in the attached images). When I attempt to change its parameters, it appears blank, and while that’s not entirely new for me, nothing I input works
Check the text file for the code of the infobox
