Phase names replaced by their first section name in template overview

[TheOldGogo]

Describe the bug
The template overview displays the wrong name for the different phases of the plan. Namely it displays the name of the first section of the phase instead of the name of the phase itself.

To Reproduce
Steps to reproduce the behavior:
0. Create a template with multiple phases

1. Go to 'admin'
2. Click on 'template'
3. Click on your template
4. Stay on the 'template details' tab
5. Scroll down to 'template overview'
6. See error

Expected behavior
In the template overview, you would expect each phase to be named by ... its name... (in my example on the screenshot it should be "Phase 1: Data Management Plan" for the first phase)

Instead it shows the name of the first section of the phase (for example in my case "Personal Information" for the first phase).

It's not a big deal for daily use. But I'd like to use the overview to communicate what we want from DMP to executives, which is not possible when my 3 phases are called "Personal information", "Data Types " and "Retention Period " instead of "Phase 1: Data Management Plan", "Phase 2: Storage and Preservation of Mature data" and "Phase 3: Closure - data inheritence"
