No empty combobox item in preset names for deleting values

[gaben]

What steps will reproduce the problem?

1. Have two objects with the same type
2. Add a name for one of them
3. Select both
4. Open the preset editor and check name options

What is the expected result?

Two combobox options. One name you added in step 2 and an empty item for deleting the value.

What happens instead?

Only the name listed, deleting is not possible by selecting the empty value.

Please provide any additional information below. Attach a screenshot if possible.

Other comboboxes don't seem affected. Check for example the bridge preset with levels, it has the empty item at the bottom of the list.
