names don't show in Name Manager but do in vba

I was looping through all the names in my workbook and noticed there are a couple names that do not show up in the name manager.
I am copying sheets from one workbook to a main workbook i dont know if that could cause something.

What are these, why are they there and is it okay to delete them? I really dont understand why there not listed in the name manger.

here are a list of the names and the line under the name is what they refer to, the bolded ones do not show up in my name manager.

thanks

are these (filterdatebase, xlfn) just created by excel similar to a print area kind of thing?
i didnt want to delete the xlfn ones because i didnt know if that was something excel needed. i figured the filterdatabase ones get created when you perform a filter action or sort of something like that.

Well i'm gonna go with the _xlfn.IFERROR and _xlfn.NUMBERVALUE names should not be delete because i tried to delete them in vba and it wont let you.

if anyone knows how/why they get created i would like to know.

thanks
