Prombt gets altered without Autoprombt

When looking in History at my Prombts I saw that my Prombts get altered without using Autoprombt.
Examples:
I wrote:
inter-mixed , paint-splashes, munching on
What is stored:
intermingled, paint splatters, nibbling at
Besides some minor typing errors got corrected.

That's confusing has something changed in the Background I never observed this before?🤔

The same Prombt rendered 5 times gives 5 slightly different stored Prombts. Then I looked at the Prombt for my celebration Pic which already has 1800Signs but stored are sometimes around 1900 Signs
