Minecraft is not saving selected player model

I am sorry if this is a duplicate

I selected the normal steve skin in the profile settings of my account, this works also fine, as long as I have an internet connection, but when you either

• Enter a world, you will see for a brief moment the Alex skin (with internet connection)
• Have no internet connection you get the Alex skin
  This is definitely a bug, first because I didn't select the Alex skin...
