Hi @MH3 ,
Did you set your description field like this?

If so, that's the reason why the data in that field display like that in your gallery.
Text in this kind of field is actually html text. If you display it in label, it will display html tags, which you think as strange characters.
You just need to insert a html text inside your gallery , then set this html text's HtmlText:
ThisItem.multext
On your side, you should use :
ThisItem.Description
Then it will look normally.

Best regards,
