Customization causes the form to open in the middle of the page

Version 2021.1.8
I sat in on an Application Studio training session that showed how to bypass the Landing Page on a Form. I applied this ‘SkipLanding’ customization to the Supplier Form. Now, when I enter the Supplier ID and hit tab, the form opens in the middle of the page.
I’ve deleted the layer twice and started over. Each time I remake the customization, I get the same results. (another little quirk is that the ‘skipped’ landing page does open for a half second, rather than being entirely skipped, but that’s minor)
How can I make sure the form opens at the beginning?
