Portfolio: When adding new "Project type" in the menu, it's switched to "Tag"

[blazevivan]

Steps to reproduce

Here is a short video: http://cld.wthms.co/NFvOYp

What I expected

To see the Project type in the menu

What happened instead

Project type is automatically switched to Tag

Browser / OS version

Chrome

Context / Source

I was not able to reproduce this case on my test site. I assume there was lack of categories and tags. What might be the issue here is that Tag used for a post is overriding the name of the Project type, as they have the same name in both cases. My workaround was to add a Custom link in the menu: https://peterburt.co.uk/project-type/drawing/

Reproduced on test site: https://senffbugreportsprojecttypes.wordpress.com/tag/fail/

See: http://prntscr.com/i3b6ui

Adding a tag "Fail" adds the correct link, e.g. https://senffbugreportsprojecttypes.wordpress.com/tag/fail/ Adding a Project type "Fail" adds the same link (instead of https://senffbugreportsprojecttypes.wordpress.com/project-type/fail/ )

Encountered same issue in this ticket: 991809-t

Reproduced in my test site:

1. Added portfolio project with type TestProjectType.
2. Went to Customizer and was able to add it as a Project Type menu item.
3. Deleted menu item.
4. Added a post and created TestProjectType category.
5. Returned to Customizer and tried adding as Project Type, but it appeared as Category instead.

Encountered here too #4468151-hc and reproduced on my test site:

1. Create a post category and project type with the same name, example 'Photography'
2. Add the post category to your menu and save
3. Add the project type to your menu and it changes to the post category.

I don't think this is related to Calypso, right? Closing as duplicate (moved).
