"Add your own library" feature is not running

[nambleyeo]

Describe the bug
Hello,
I'm just in the process of trying/testing your tool and I'm block in the first test of my usability experience: exporting my own risk matrix in other to start importing risk. Since the risk provided by default doesn't fit my needs, I decided to use your converter with and excel file that gave me a resulting yaml file which I then tried imported to Cisco assistant unsuccessfully.

To Reproduce
Steps to reproduce the behavior:

1. Go to '.Governance > Risk matrices'
2. Click on 'Import matrices'
3. Scroll down to up to the bottom you have button "choisir un fichier" (Select a file)
4. from there a window open where you can select the file for the desired folder
5. The name of the file file appear in the display box
6. When you finally click on "Add" the text displayed in the display box change to "Aucun fichier sélectionner" as the action flushed the file you just selected (error n°1)
7. When you go to "Loaded libraries" you can notice that your file hasn't been upload

Expected behavior
I expected after clicking on the "Add" button to have a message indicating if my library was successfully uploaded or not; and if not some hints on what is wrong with my file.
And finally find my uploaded library in the "Loaded Library" section

Hi @nambleyeo, is it possible for you to share your Excel here or anywhere else if you have some senstive data, just to test it on my side as well.
