Have a pro check this. If you do short drives like under 5 miles this will probably happen, no time to warm the engine up. Or you have abad or bad injectors.

If you are running LPG, then the Fuel Injection System should not
be pressurized. And not cause fuel to leak past an Injector. A
faulty Fuel Pressure Regulator, can leak gasoline into the intake
manifold via the vacuum hose that is attached to it. But again,
pressurized fuel in the rail needs to be there in order for that to happen.

Make sure that when you are running on LPG, that your Gasoline
fuel pump is not running.
