When one bottle of propane is empty the indicator gauge does NOT flip to red, until both tanks are empty. Then flips to red.

If you have both tank valves open and are therefore using the tanks simultaneously with the inidcator lever set mid way between the tanks then of course that indicator will only show red once both tanks are empty. The alternative is to open the valve on just one tank and use them sequentially, setting the lever to point towards the in use tank ... once it empties the indicator will turn red and you'll know to close it's valve, open the second tank valve, and move the indicator lever to new in use tank, at which point the indicator will once again turn green. Surely your dealer must have explained the difference between using your tanks simultaneously or sequentially.
