Twin Sprites Different Size when displayed

[JHershey69]

I have created 2 sprites of the same size and filled each with a triangle. The first the triangle points up, the second the triangle points down. My code:

tri1.createSprite(8,8);
tri2.createSprite(8, 8);

// Triangle points up and is top triangle
tri1.fillSprite(TFT_BLACK);
tri1.fillTriangle(4, 0, 0, 8, 8, 8, TFT_WHITE);
tri1.pushToSprite(&spr, 165, 18, TFT_BLACK);

//Triangle points down and is bottom triangle
tri2.fillSprite(TFT_BLACK);
tri2.fillTriangle(0, 0, 8, 0, 4, 8, TFT_WHITE);
tri2.pushToSprite(&spr, 166, 32, TFT_BLACK);

That second sprite appears larger when displayed, whether it is pushed first or second.

What can I learn here?

TIA.
