Your screenshot looks like it came from a section in your custom form. If this is the case, I recommend you talk to your system/group admin about whether or not these fields continue to be needed.
Some of the things admins have done in our instance are:
* store fields like this in a separate "universal" form, so that it's not as visible
* store it in a section and then "hide" the section unless a particular checkbox field is selected
* put access permissions on the section so that only admins can see it
