UPDATE ON THIS!

On the "Add Terms" under Forms in the Studio, I saw 2 buttons Publish n Submit, my initial attempt was with the Publish button since it was activated by default, the results were as first reported.

However, in another attempt enabling the Submit and disabling Publish, the App works fine.

I also discovered that the Dashboard Counter for Glossary only report 1 entry instead of 2, the first entry was not recorded even though it was uploaded successfully.

The Glossary view page doesn't display any SUBMENU yet. So this is still something to check.
