Re: Adjust TXV
Check evaporator for cleanness and enough air/water. Check fan/pump proper function/direction. Check if it is frosted and defrost it. Check if you have enough load.
If anything above is wrong, you cannot have enough heat to boil all refrigerant.
Check TEV bulb position. Check your subcooling is below 8.5K at design temperature and at 40°C condensation temperature (indication of overcharge).

Re: Adjust TXV
The system is possibly overcharged causing floodback or orifice oversized for application.

Re: Adjust TXV
Do you have an accumulator?
You can try with increase the superheat setting (clockwise the superheat setting screw on TXV, every 1/2 round after half hour running by measure the acture SH.)
