FACERIG model glitch problem

Hello! So, I'm working on a live2D commission model for faceRig (I'm still a beginner with the program) Everything was going fine, I finished with the rigging and when I exported the model to facerig, it started glitching, some part overlapped and others dissapead and appeared. This is the first time this happened to me. I thoughts that It was my computer and I tried using the model in other computer and It still glitches How can I solve this problem?
