1 page has multiple canonical URLs - one for http one for https

hey guys. I might need a little bit of help here. I found that one page of mine has two canonical tags.

While I only have 1 custom code for the first tag, I have no idea where the sec canonical tag is coming from.

Can anyone help me to debug the issue?
