Steven ZahmRight now, Form does not have a “Dates” metabox but it does have a metabox to allow the input of the Anniversary and Birthday. That metabox is off by default, but can be turned on.
In the admin, the Date metabox, you collapsed it. If you hover your mouse on the right hand side of the bar that says “Dates” you can click to toggle it to open. This is a common feature for all properly coded WordPress metaboxes. Just incase you run into this somewhere else in the WordPress admin.
Also in the admin, the category metabox has a different look and function. By default it shows on the right hand side in a second narrow column. Since the admin organization in completely customizable it’s hard to say where it might be presently; but if you do not see it at all, in the upper right corner there is a “Screen Options” tab. Click that and see if the Category metabox was toggled off. This too is a standard WordPress admin feature that many plugins utilize. So if you ever can not locate something that should be on the screen, check there first.
I hope that helps.
