Rising Tempest - Counts Skills instead of Elements

Please see images attached. Both are "Lightning" skills, with no support gems attached. Yet elemental damage for Quarterstaff Strike goes up by 12% MORE for each SKILL used instead, while word for Rising Tempest says 12% more for each skill of a DIFFERENT element used (recently).

Image 1: Base case
Light max hit is 359


Image 2: Using Tempest Flurry (Lightning Element)
Light max hit is 403 (359 * 1.12 rounded up)


Image 3: Using Tempest Flurry followed by Siphoning Strike (both Lightning)
Light max hit is 446 (359 * 1.12 * 1.12 rounded kinda down? idk)


Either description needs fixing, or gem needs fixing.

I noticed this bug with Spark, it's not each SKILL, it's each skill of the SAME Element, opposite of what the gem states. With this support in place, skills like fire wall or Frost wall does not increase tool tip damage of Spark, but Spark itself DOES increase damage (as soon as you start casting, dmg increases), so does Orb of Storm, Lightning Warp, Lightning conduit, and Conductivity, anything with Lightning tag it seems, will increase dmg of Spark within 4 sec of casting, including Spark itself, and they do stack within 4 sec.
