VWAP moves positions when switching positions

It appears when switching between different timeframes that the VWAP indicator will fluctuate its position.

I was able to reproduce the issue by dropping down into a 30second chart, zooming into a small area, switching to 30 minutes then back to 30 seconds and zooming out once again. You'll see the VWAP is at a specific level but as you zoom out, you'll notice the VWAP move into its correct place. It's almost like the higher time frame VWAP is being persisted through to the lower time frames and unless you mess around with your zoom on the chart, it wont position it.

This is causing quite a bit of errors for me in my trading as I am thinking the price is near the VWAP.
