Core Shell File Chooser Stale

I have noticed that sometimes when I open the Finder by right-clicking in a Core Shell window and choosing 'Upload to"[path]"', the file list shown is out-of-date. Even though I know I saved the file after updating it, I am still shown the timestamp from before.
Does Core Shell cache the file list? Or is this a macOS problem?
I cannot provide steps to reproduce this as it seems to be random.
Thanks for your help, keep safe.

For sandboxing and security reasons, the open file dialog is managed by the Powerbox of macOS, Core Shell creates, shows and destroys it indirectly.

So, it is absolutely an issue of macOS.
