Forward doesn't move right

I didn’t know how to explain it properly, but if I use the bar forward, sometimes I get two candles, sometimes price action remains at the last candle, and closes it to give me a double candle.

So to make sense of what i mean i got my mad video skills out and created a video to show you what i mean😎

Maybe i am doing something wrong here, either way it is annoying to say the least.
