Removing lines from sheet and NPC lvl

Hi all, I've got a pretty simple question, I hope :) Occasionally, I have added an empty line to, for example, the spell list of a NPC. But I cannot find a way to remove it completely (only empty it, but it's still there). The same goes for character sheets, for example if they lose an item, how can I delete the whole section of that item? Next to that, my party is being confronted by a group where I would like to let the NPC grow in lvl just as well as the party. Is there a way to lvl up an NPC? Just increasing the CR is not doing the trick :) Thx.

You should probably post what game system/character sheet you are using.

Also, what do you mean by "add an empty line"? Do mean, add a spell but not fill out any of the fields, for instance?

Sorry, more info: DND 5e, OGL template What I mean is empty line in the character sheet as depicted below. What is the quickest way to remove them?

On this sheet, Repeating Sections have the "plus" sign to add more rows, and the "lock" icon to modify the section(on other sheets they say "add" and "modify" respectively).  If you press the "lock" icon, you will get the option to remove individual rows from the appearing "garbage can" icons. You can also rearrange the order of the rows by dragging them up/down. When you're finished with your changes, press the "lock" icon again to lock down the section. The wiki page for the sheet you're using, has a section detailing this as well: DnD5E by Roll20 Sheet: The Padlock Button and Organizing Elements 5E OGL Sheet Padlock GIF

Thx. The lock icon felt different when I first used it, but apparantly I missed it. Thx for helping.
