I can take a look into this today and see if we can get it fixed for you. Do you have the name of the course or a pkg file that contains the issue? Once I run through it I’ll be able to let you know if it can be fixed immediately or in our next maintenance release.
If you can also let me know the org name it’s under, that would help. Thanks!
The option of specifying a number/value for numbered lists should be available in the Home tab -> List Properties icon next to the number and bullet lists icons.
You can either select the whole text block object to change every numbered list inside OR highlight specific lines of text during editing and then clicking on the List Properties icon. From your example, say you had numbers 1-15 number lists on the text block, you can simply copy paste this into the next page. Once its in there, have the text block selected, go to List Properties and in the dialogue specify “Starting Value” to be 16 for example and the list should update to 16-31.
I’ve attached a screenshot of where the List Property Icon is located. You can modify the “types”, “size”, “starting value” and “color” of the bullet/numbered lists here also independently from the text.
