Hi Alex
See screen recording below.

When trying to add zip packages through the front end, as soon as I click to add package the screen jumps to the bottom of the browser window and only a part of the dialogue box is visible, making it impossible to add information or to use the window. Tried it with Google Chrome, MS Edge and Internet Explorer - same result.
Well this is the old front end edit screen which is not supported or recommeded by us now as the wordpress itself does not maintains the front end editor .
So please add the package from course front end edit like this :
