Why a custom added button in "more-tiddler-action" doesn't have its caption displayed in the dropdown

[Sobriety]

The custom made buttons added to the View Toolbar, if viewed in the dropdown of $:/core/ui/Buttons/more-tiddler-actions don’t have the caption.
Looking at how the other buttons in the core are structured, for example $:/core/ui/Buttons/permaview I see that there are two fields:

1. caption: {{$:/core/images/permaview-button}} {{$:/language/Buttons/Permaview/Caption}}

2. description: {{$:/language/Buttons/Permaview/Hint}}

I think I have to fill the caption field, and so I did, but nothing appears. (The only difference is that in the caption field I don’t have a language tiddler transcluded here, but but directly the words that I would like to be displayed). How should I do to have the words in the dropdown?

Attaching an image to visualize the problem

The text shown in the more menu comes from the “description” field.

I filled that one too, but can’t see it

How did you write it? Can you show the tiddler code or a screenshot in edit-mode where we can see the fields?

[Sobriety]

Yes, here

Title: Move tiddler down
text:

\whitespace trim
<$button class=<<tv-config-toolbar-class>> tooltip="Move Tiddler Down">{{$:/images/font-awesome/solid/arrow-down}}<$action-listops $tiddler='$:/StoryList' $field='list' $subfilter='[list[$:/StoryList]move<currentTiddler>]'/></$button>

caption: {{$:/images/font-awesome/solid/arrow-down}} Move Tiddler Down
description: Move the current tiddler down in the story river

Hmm, May be a visibility setting problem. Need to have a closer look

You know that the Open sidebar contains draggable items? IMO it does the same thing

Can you see your buttons at : ControlPanel → Appearence → Toolbars → View Toolbar?

[pmario]

I think your text is missing the caption or description info. See the image for the Clone - button

[Sobriety]

Yes! It was exactly that, thank you pmario!
