Redstone Repeater Bug, Primed TNT Not Falling Straight Down

Redstone repeaters start on what looks like 4 ticks and with each click decrease towards 1 tick. But the delay values act the opposite way, when they look like 4 ticks they are 1 tick and when they look like 1 they are actually 4.

TNT also shifts when it falls. It doesn't fall straight down.
