Steps to reproduce

I would assume if you cloned the project to another machine it may have the same issue (I dont have another machine to clone to)

What is expected?

When I review any other project in Vue UI in the plugins view I can download the updates by clicking the download arrow icon, when there is a newer version.

This project says it stuck on v 3.12.1

Also the add Vuex and Router buttons appear at the top but they are already included in the dependencies section

What is actually happening?

There is not download icon

---

Some reason the project just started not showing the download arrow
