Random intercept random slope vs Random intercept model

I had a question regarding the comparison between random intercept and random slope model. I wondel why the AIC and BIC of the random intercept and random slope is better than the random intercept while the variation of the random intercept and random slope model is trivial and the correlation between random intercept and random slope is high. I have to say in theis model the log form of the outcome is used.
