You have to set an overlap parameter for those 3 skills. The scroll/item or whatever doesn't matter.
The skill will be prompt listed as "used" and any other string (skill) sharing the same action_overlap definition will deny being imbued to your character's buff-tray.
You should use the same action_overlap like the other imbues are using, this will prevent stacking 2 of the same kind, or otherkind.
USE <Database>
UPDATE _RefSkill
SET Action_Overlap = 1
WHERE <either ID or string of your new skills - condition>
