Mao, I am new to KiCad so this is just a guess, but have you placed all the sections of the 74HC00 that is connected to 3.3v? This part has sections A-F, and each section has the hidden VCC and Gnd pins. If you have not placed all the sections on the schematic, perhaps KiCad is picking up the VCC from the unused sections and assuming they are all tied together. You might try placing all 6 sections of the 3.3v 74HC00 on the schematic and show and connect VCC on all 6 to 3.3v.
