Drag and Drop a markdown file into a markdown document

Hi,
If I drag and drop a markdown file into the text field (edit window) of another markdown file within DTP, nothing happens. The normal behavior should be, that an item link should be inserted in the markdown document. In my case nothing happens, no item link is inserted. It works when drag and drop an image into the markdown docment, but not with another markdown document. I have contacted the devonthink support and @BLUEFROG was very helpful, but the support could not reproduce my problem. Is anything out there observing the same behavior? Or has anyone or even @cgrunenberg an idea what might causing this? Otherwise I will wait for the next update, maybe it’s fixed then. Thanks in advance!
