Drop-down list label dissapearing

We are using a standard Kentico bizform that has a few text inputs and a few dropdowns. Every form element utilizes a Resource String from the Localizations tab to fetch the label value.

We have an issue where the labels related to the dropdown elements appear for a second and then the entire label HTML element is deleted. There don't seem to be any console errors that might indicate what the issue is. This issue does not happen for regular text fields.

Label value defined in form builder: {$Form.Topic.Label$}
