simplytest.me offering inconsistent version choices depending on form entry sequence

Problem / Motivation

Which versions of core and modules varies depending on what order I enter the request on the form. This appears to be an intermittent problem.

Steps (sequence 1):

1. Go to Simplytest website
2. In the Evaluate Drupal Projects field, enter Core
3. In the auto complete, choose Drupal core
4. Expand the version drop-down menu

Result: The first entry in the latest section is 10.4.4 (10.x)

Steps (sequence 2):

1. Go to Simplytest website
2. In the Evaluate Drupal Projects field, enter Redirect
3. In the auto complete, choose Redirect
4. Click Advanced options

Result: The first time I tried this, it displayed 11.1.3. The second time I tried this it displayed 10.4.4. The two tries were within 10 minutes of each other.
