Navball Markers are glitched

[phantom000]

I am coming back from Mun, i set up a burn to take me back towards Kerbin. I set the SAS, wait until T-10, the maneuver marker and the prograde marker are right on top of each other, but then when i fire the engine they start moving apart and my Delta-V indicator counts up instead of down. My new orbit is completely screwed up. 

I tried to get around the problem by setting it to Stability Assist but that did not help. I also uninstalled all mods in case they were interfering and i tried restarting KSP but nothing worked.

Has anyone else been having similar problems.

The most likely thing is your engines aren't thrusting through your center of mass, in the direction your command module is pointing.

A picture of your ship, perhaps while thrusting, could help us help you more.

This happens to me sometimes, when the ship is controlled from something pointing backwards. This can happen e.g. If your the probe you decouple does not contain the root part and your decoupler on it is pointing backwards. Simply right click on your pod/probecore amd click "comtrol from here"

Yeah, I forgot to set the lander can back to 'control from here' I knew it was not my lander because i had been to Mun and back several times with that ship and never had that problem before.
