Problem with incrementing Program Counter

Hello, I am a begginer VHDL coder and I am making a mips processor. My issue is that I can not seem to get my Program Counter (PC) to increment correctly. It should start with all 32 bits 0's and then add 4 to it at the start of every fetch operation ( I believe) so it should increment , x"00000000" to x"00000004" to x"00000008" and so on until it is reset. It seems with my current configuartion it loads 4 and then shifts it to the left so it may be an issue with my alu control. I will add my QAR file for the project and a picture of the datapath. The mips_tb should be the testbench that is used and you will need to add signals from the entities accordingly. Thanks
