Material/Labor/Equipment/Other Window Broken on Safari

Good morning gents,

I (and probably the three other Mac users out there) am having a difficulty today. The popout window for creating and/or editing child items like Materials, Labor, Subs, etc is broken.

When tryig to create a new child item or edit an existing one, I get the following:

This is:

System Version: macOS 26.4.1 (25E253)

Kernel Version: Darwin 25.4.0

Safari Version 26.4

The problem doesn't occur on a Chromium-based browser like Chrome or Edge.
