[Bug]: Unselected checkpoint is loaded before generation

[isr431]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

When I generate an image, a unselected checkpoint is being loaded instead incorrectly. This happens randomly and isn't consistent. The checkpoint being loaded is the default model and the first model in the list, so it could be either causing the problem.

Steps to reproduce the problem

1. Select a checkpoint
2. Generate an image

What should have happened?

WebUI should only use the checkpoint loaded, not load another checkpoint without the user explicitly setting it to do so.

What browsers do you use to access the UI ?

Mozilla Firefox, Google Chrome
