## Description

### Steps to reproduce

<br>

1.  Login as an administrator
    
2.  Navigate to Administration -&gt; Design -&gt; PDF export font
    
3.  Upload a .ttf file for a new regular font
    
4.  Try to upload a second .ttf file for a bold font
    

### What is the buggy behavior?

<br>

*   When the second file is uploaded, an error &quot;is not a valid TTF font file&quot; shows up
    
*   The first uploaded file is not visible in the UI anymore
    
*   When the second uploaded file is deleted, the first appears again
    
*   It is not possible to generate a PDF demo anymore
    

### What is the expected behavior?

<br>

1.  It is possible to upload .ttf files to all four offered options
    
2.  A PDF demo can be generated
