The machine name hasn't generated when the Label contains a special character(for example: -, #, &, @, /, * [not the full list]) on the 'Add migration group' form.
On the 'Add migration group' form type text into the Label field and type a special character(for example: -, #, &, @, /, * [not the full list]), then the characters that are after the special character won't be in the generated machine name.
Copy and paste a string to the Label field that contains at least 1 special character(for example: -, #, &, @, /, * [not the full list]) and the machine name won't be generated.
1. Go to the '/admin/structure/migrate/add' page
2. Start typing a text to the Label field
3. Type a special character(for example: -, #, &, @, /, * [not the full list])
4. Type more letters or number into the field
5. Check the generated machine name beside the Label field
1. Go to the '/admin/structure/migrate/add' page
2. Create a string with a special character, for example: 'Some#thing'
3. Paste the string into the Label field
4. Check the machine name beside the Label field

Hi Gergo,
It is working as expected. Drupal does not accept special characters in machine names and replaces them with underscores if they appear between letters and numbers. Please find the attached screenshot for reference.
Thanks.
Thanks Gaurav Gupta! Then the problem is something else in our code.
