Missing search result

I am currently testing OJS Here I have trouble transferring files from Review to Copyediting. When I click on ‘Accept Submission’, the following window first appears:

Accept submission1

Here I select ‘Do not send an email notification’ and click on the button ‘Next: Select Files for Copyediting’
The following window will then appear:

Accept submission2

Although I have done various searches, no search result comes up and I just have to click on the ‘Record Editorial Decision’ button. However, this means that no files are transferred to the next step ‘Copyediting’
Is this a problem you already know about?
