Problems in Google Chrome with landing page ""

After navigating through my new presell page it directs me to the following landing page.

I noticed that the “Select timezone” field and the “Select country” field are not working correctly.
When I click in either field the drop down is very small and there is no content. I’ve provided a screenshot of the landing page when selecting the “Select timezone” field.

This issue appears to only affect Google Chrome. Safari and Firefox are not affected. I am running macOS Version 10.14.3 (18D109) and Chrome Version 75.0.3770.80 (Official Build) (64-bit)
