Do you mean time time entry report?
And give us more information: [[Submissions]].
--------------------------------------------------------------------------------
Yes, I mean the time entry report in general, not for a particular project.

<pre>
Environment:
Redmine version 3.0.1.stable.14155
Ruby version 2.2.1-p85 (2015-02-26) [x86_64-linux]
Rails version 4.2.1
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.8
Git 1.9.1
Filesystem
</pre>

here is an extract of my database for enumerations. I found several entries for the same name, which are linked to different projects:
<pre>
mysql> select * from enumerations order by name;
+-----+-------------------------------+----------+------------+-------------------+--------+------------+-----------+---------------+
| id | name | position | is_default | type | active | project_id | parent_id | position_name |
+-----+-------------------------------+----------+------------+-------------------+--------+------------+-----------+---------------+
| 11 | Specification | 13 | 0 | TimeEntryActivity | 1 | NULL | NULL | NULL |

| 238 | Training | 182 | 0 | TimeEntryActivity | 0 | 55 | 19 | NULL |
</pre>

--------------------------------------------------------------------------------
Here is what I get for an activity called "Other":

!report_activities.PNG!

Now, If I add the "Projects" column (Each line is a different project):

!report_activities_projects.PNG!

Could reproduce the bug as described on a freshly launched Bitnami redmine demo instance (https://bitnami.com/launch/redmine/aws/now):

<pre>
Environment:
Redmine version 3.2.1.stable
Ruby version 2.1.8-p440 (2015-12-16) [x86_64-linux]
Rails version 4.2.5.2
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.13
Cvs 1.12.13
Git 2.6.1
Filesystem
Redmine plugins:
no plugin installed
</pre>

Steps to follow using a fresh redmine install:

Create a new activity, do not check "Active":

!1.PNG!

Create two projects "Test A" and "Test B". Don't need to set any specific param, appart from the "Activities (Time tracking)" tab. Do as follows for each project, then save:

!2.PNG!

Now that the activities are activated, time to log some time on each project:

!3.PNG!

and

!4.PNG!

Then click 1, then 2 on following:

!5.PNG!

Then click on the "Report" Button

!6.PNG!

Then click "Activity" in the Add section:

!7.PNG!

Result:

!8.PNG!

I hope these instructions are clear enough to be reproduced :)

up

This still happens on Redmine 3.3.0.stable
--------------------------------------------------------------------------------
I also confirmed(trunk: r21299). I think the following patch will solve it.

<pre><code class="diff">

Setting the target version to 4.2.4.

Committed the patch. Thank you for your contribution.
