Photos edited in photoshop are not saving with changes into lightroom

After doing an update with camera raw, my software is not working like it had. I start in lightroom and make slight changes but then tranfer to photoshop to do major things and use actions I like. I then save and it usually goes right back to lightroom next to orignal with changes made. Now when it saves it looks like its almost black and white, lost so much saturation. I can not figure out how to fix this. Please help.... Have so many sessions to edit and don't have the time to keep googling trying to figure it out. ugh
