XP does not collect in Minecraft?

I recently proved my skill again and killed a creeper without it exploding😎.

In any case, it is not about that. He just dropped balls of experience (as always) and as it should be, they collected. A step further, I noticed that there was still one left and ran towards her. I then went on again and noticed that it hadn't collected. I then noticed that she was following me but could not be collected. I stopped, the ball came to me and just lay between my legs.

What's this? Is this a bug? Can I somehow collect them?

Get out of the world again and back in there seems to be a bug.
