[Bug] conditional Segments with "continent", the NOT (conditional filter) is broken

[atom-box]

What happened?

For continent IS NOT ______ the result is the opposite of what is expected

These segments all fail

• continent IS NOT eur (returns countries like Sweden and Germany)
• continent IS NOT afr (returns countries like Zaire, Zimbabwe, and Sudan)
• continent IS NOT amn (returns Canada, Mexico, et al)

Other conditionals work fine (IS eur, STARTS WITH eur, CONTAINS eur, …)
Other metrics work fine (IS NOT sweden, IS NOT stockholm)

What should happen?

The opposite of what happened should happen.

How can this be reproduced?

To reproduce, make a custom report. Add any filter as shown in the screenshots below.

Even easier:

1. Go to Visitors >> Visits Log or Visitors >> Locations
2. Make a new segment: (continent) (is not) (eur)
3. Hit test.

This bug is still present.

I work for Matomo - and can reproduce it.

Another user emailed today about it.

It is easy to reproduce (see my screenshot).
The fix seems to just be to swap IS and NOT.

Dear team
This bug, even thought has an easy overcome, is not a final solution for end-users, that will need to re-do their Custom Reports after the bug is fixed. If we manage many websites then this is a tedious work, and also "invalidations" must be executed.

I hope this bug is fixed soon.
