To use the <panel> tag in an infobox it needs to separate the tabs with the <section> tags. I put the <data> tags inside the <section> tags like the Infobox help page suggests.
When you use a <data> tag, it appears when adding a new infobox to a page as a blank slot that you can fill with data, like any template. However, whe the <data> tag is inside the <section> tag, it will appear normally for some time, then someday whenever I add a new infobox to a page only the parameters related to <data> tags that are outside the <panel> code (Most commonly the image) are the only ones that appear on the screen to insert data on templates. While this can be solved by knowing the name of the parameters, this is complicated for infoboxes for many parameters and is all around poor for new users who are not well-acquainted with the wiki.
What causes this, and how do I solve it?
