How to display the labels of input fields?

I do have another concern: the labels (such as Email or Phone Number) for each textbox are no longer appearing in the previews of the application. Instead, they are embedded within the textbook, How can I fix this?

Those are not Labels but rather Placeholders.

Your Labels were hidden on the ADVANCED DESIGNER when I checked. If you wish to show the labels, do the following:

Click DESIGN at the top > ADVANCED DESIGNER > then on the LABEL STYLES section, set it to NORMAL LABELS > SAVE

Give it a spin and let us know if you'd need more help.

Thank you, it worked!
