Redmine

We used Redmine 3.2. There was a field on Issue to enter Spent time and select activity, such as Research Issue, Reproduce Issue, Communicate with Customer, etc.

Each entry would total to list the total time spent on the Issue, and list it in "Spent time" field. This field
is clickable to show individual Spent time entries with a Total time.

In redmine 4.0.1, Spent time is a tab at the top of the Project.

When I click on the tab, and edit Spent time for an Issue, it is not a total.

For example, I add
2 hours 02/19/2019 Reproduce and/or test
2 hours 02/19/2019 Documentation

but it shows only 2.00 hours on the Details page.

Have I misconfigured something?

I would like to have Spent time listed on each issue. Is this still possible or do I need to use 3.n?

Thank you,
Anne
