Can't drag and drop selected text from other programs

[lwksaw]

Hi, I can't drag selected text in another program (like Xfce's text editor, Mousepad) into TextMaker, Presentations or PlanMaker. It looks like they try to open a new file, instead of pasting the selected text.

Steps to reproduce:
1. Select text from another program (i.e. Firefox, PDF file, Text Editor, etc).
2. Drag the selected text into a document in TextMaker, Presentations or PlanMaker.
3. Instead of pasting selected text, these programs understands that you are trying to open a file.

I recorded a video showing the steps above: https://youtu.be/_ggUSFdmP3A

I'm using Xubuntu 20.04, Xfce 4.16 and Softmaker Office 2021 (3104).
