What is the problem with avatar picture?

Hi I am Peter - please help me.

Maybe you will know - why my steemit my profile avatar picture: (the small round one) do not show on anywhere?

I had this problem before, than I have changed to one which appeared instantaneously, and now wanting to change it to a different one I lost it again.

Is it because of their size or something?

Other thing is these notification numbers at feed replies and so on where on for few days, and now gone - anyone of you has it, any ideas, why do I not have it anymore?

Please help :)

Much appreciated.

Love and peace :)

Peter.
