After Compression, "Optimize images" Error Page Load Worse

Hi, when I'm using the free version.. the "Optimized Images" from Google Pagespeed score in mobile is 66, now I used the premium version and I see the score got very low @ score of 47.. and the "Optimize images" is in the top 'Should Fix', before it was on the 'Consider Fixing'.
I hope you can help me..
