Previouly (in 2.6lts maybe after)

Preview group set relevance =1 to Group (force) : see code : https://github.com/LimeSurvey/LimeSurvey/blob/e2a9ca1adfa9d5693409566b0b60f07e9f3a114a/application/helpers/expressions/em_manager_helper.php#L3740-L3741

               if($this->sPreviewMode=='question') $fielddata['relevance']=1;
                if($this->sPreviewMode=='group') $fielddata['grelevance']=1;

But no update of question relevance :)
With /sid/347371/gid/859?showQuestion=Y : you can force show the 2nd question
Same with array_filter using GET for prefill values.

@DenisChenu:
This issue first occurred after your commit:
https://github.com/LimeSurvey/LimeSurvey/commit/fa2fae1efa728f569cbcb98dae52fea5a8778c77

Do you have any workaround for this?

@dominikvitt : it's false

I just git checkout 392b869292012b19b3606e711924cc2fc00b01c6 , fix DB for owner_uid
And see screenshot

The issue with this it's not happen everytime … see comment on https://bugs.limesurvey.org/view.php?id=14936

If relevance is OK (some times it was)

The main issue is there are no ExpressionManager javascript inside survey

I think EM is not initialized : https://github.com/LimeSurvey/LimeSurvey/blob/e2a9ca1adfa9d5693409566b0b60f07e9f3a114a/application/helpers/expressions/em_manager_helper.php#L7257

It's the reason why it seems to happen after reset the session.

If you have already a EM session : it was not resetted (and can be old …) .

To check before https://github.com/LimeSurvey/LimeSurvey/commit/fa2fae1efa728f569cbcb98dae52fea5a8778c77 : you must NOT test survey or check survey logic file etc … before testing …

I'm only testing with attached lss file.
When I tried to preview G02Q02 question after hard reset on https://github.com/LimeSurvey/LimeSurvey/commit/fa2fae1efa728f569cbcb98dae52fea5a8778c77 commit, it doesn't work.
When I tried to preview with hard reset one commit before , it works.

I can reproduce this behaviour at any time.

Please try to go one commit before.

Yes, 392b869292012b19b3606e711924cc2fc00b01c6 is one commit before.

But try with :

• Copy the preview link on text editor
• Close your browser
• Open browser
• Log in
• Paste the preview link
  => Since it's same than reset the surveyid session : you have the same issue :).

Ready to go : https://github.com/LimeSurvey/LimeSurvey/pull/1298

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=29009
