I have the same problem. After I put extra space to the attribute name, it’s appearing twice on the New Event page.
Event after I remove the attribs from the code, the attrib fields are still showing on the event registration page. it seems like deletion doesn’t work
i hv tried to add the attrib field but the alignment doesn’t seem to be correct.
pls refer my website http://badmintonzone.asia/ and try on the create event -> add new
