New Clutch kit installed weird pedal travel
 

I just installed a new clutch kit in my car the clutch pedal is working weird. When i first start the car in the morning the pedal is in the right position by the time i get to work the pedal is all the way to the top. (no clutch slippage, new throw out bearing, pilot bearing and pressure plate) Mazda just replaced the engine 2000 kms ago and thoughts?
