It seems normal to me but maybe some overfitting problems may exist due to unsatisfactory parameter settings. Please try a different one (especially the learning rate) and see what's different. In fact, I also met with similar results. One technique I suggest is doing gird search or random search for some hyper-parameters but that's gonna take a long time.

Oh,Thank you very much!!,You always give me much help!

no problem
