Right click menu is not working on some records

[jbasa]

Recently we discovered that some of our computer records do not allow the right-click context menu. We use this quite a bit to save and reload forms, as I am sure many do. It's a random issue it appears.

What I would expect

What we are finding in some records

Our computer records are not touched frequently.  We only found this as the computer was End Of Life, and when editing the records encounter this.  It does not appear to be happening in Incidents, problems, or Change records. 

On the record where the menu is not working, I do see this when in Dev tools for the browser.

I do not see this appear on the records where the menu works.  I am not understanding the error or where I might look.

Any help is appreciated and I have searched the article for the same issue, though I am not able to find or resolve with the information I have found.

@jbasa 

this happens when your form is broken.

Check browser console errors

Some client script, ui policy is causing that error

So the last image does show a UI Policy though not sure on what that is or how to pull that info out. Why is not affecting all records

[jbasa]

One thing to add.  If I delete the computer record that has an issue with the context menus.  Create a new record for it, then it works.

Had the same error, it was a UI Policy that was incorrectly set up.
