Based on the image you provided, it looks like the text box with the border is a "Label" control, while the other text box without the border is a "Text" control.
To remove the border around the Label control, follow these steps:
- Select the Label control in the canvas app editor.
- In the Properties pane, expand the Border section.
- Set the BorderThickness property to 0.
This will remove the border around the Label control and make it look like the Text control.
Alternatively, you could change the Text control to a Label control, if you want all your fields to have the same appearance. To do this, select the Text control, right-click on it, and select "Change Control" > "Label". Then you can modify the label text to match the field name, and adjust the formatting as desired.
