Make sure that in your Zotero's preferences under "Cite" you have "Include URLs for paper articles" ticked.

Citing Medicine, 2nd edition, https://www.ncbi.nlm.nih.gov/books/NBK7281/ says:

"It is important to cite the version you saw. If you viewed an article on the Internet, do not cite it as if it were a print one. However, it may be useful to begin a citation to an Internet article by first locating all of the information needed to cite it as if it were a print article, then adding the Internet-specific items. For example:

Print information
Kaul S, Diamond GA. Good enough: a primer on the analysis and interpretation of noninferiority trials. Ann Intern Med. 2006 Jul 4;145(1):62-9.

Added Internet information (in bold)
Kaul S, Diamond GA. Good enough: a primer on the analysis and interpretation of noninferiority trials. Ann Intern Med [Internet]. 2006 Jul 4 [cited 2007 Jan 4];145(1):62-9. Available from: http://www.annals.org/cgi/reprint/145/1/62.pdf"

Nowadays, the most of articles consulted by users are in Internet, only electronic or electronic version of printed ones.

At the same time, only electronic journal articles in Zotero do not include: Type of medium [Internet], Date of citation, and Availability (captures attached).

It does sound from that as if the Internet label should be added. I’m not sure that I’ll get to it this week but it isn’t a complicated fix.

Yes we should not add the Internet label — there were many complaints about it when the label used to be included
