Seems you have found an issue with the dynamic values as the item count. I will look into it. For the time being, not using "%%RND(1,10)%%" as the Count will fix this. Also damage needs to be upper case D as in "Damage".

The damage tag is shown as lowercase in the wiki by the way, that will need updating if you're right. I am still experiencing this bug by the way.
