Refering the to help page for "To Create a Custom Drawing Seed for a Section Callout", step 3:

If you want to use the settings of an existing drawing seed, select it from the Drawing Seed drop-down list, else select (none).
If I leave the "drawing seed" field as "(none)", the "create drawing" checkbox is greyed out and unselectable. Is that a bug?

Hi Tuan,
Thanks for raising this issue. I will have some testing at my end and will share the outcome with you.

for some reason it's working now Shivam, probably just a restart is required.
