Text (Violet T in a box) cannot be part of component

I am working with a text, that has a violet T in a box in the layer panel. I need the text to be part of a component, but it does not work. The text however, is not a component as far as i can tell.

What is this T in a box? How can I make the text part of a component without recreating all these texts?
Can someone help me please :pray:

Here an image of what text I mean:

Thank you :smiley:

This is the menu that shows up when I click on it:

This is not a text layer, but Shape with text from FigJam. Objects from FigJam cannot be added to components. So you need to create new text layers using the Text tool.

Thank you :smiley:
