SplitGroup in Accessibility Inspector

Good evening!

I’ve tried to work with UI elements of my application - but it is not easy!

Accessibility Inspector define next hierarchy:

But Script Editor doesn’t see any SplitGroup.

On command

tell process “MyClient”
tell window “Submission”
UI elements
end tell
end tell

it gives me only buttons & static texts.

Does anybody knows why so happen?

Grand merci.
