HTML attribute completion using curly brackets

Say im creating a new element.

<section></section>

Now im going to add a new attribute to the element.

<section data-test></section>

As soon as I add the '=' after 'data-test' it SHOULD create quotes for me to enter the value.

However, recently it has been creating {} instead. It is driving me absolutely insane. It used to work correctly. I can't find the setting to go back to the way it was.

Please help!
