I have a stamp (blue), I have it resized the way I like it and want to duplicate that to additional blue numbers.
This can easily be achieved by holding Ctrl while clicking the number I want to clone. Works just fine unless you have the number activated first.
For this to work the focus can't be on the stamp. If so the duplication does take place, but a 3rd stamp is on top of both and it's in actual size.
It's easy to just delete the larger stamp but wanted to report this bug.
Reach out to me if you have additional questions.
