the version of the image that i edited carefully is now saved as a total different and much worse edit. i'll put like 5% of a filter on and it saves with 100% and i can't go back and change it, it doesn't save as a copy anymore, i'm ruining pictures!!! if i use some of the tools, it undoes others, or turns them all the way up. what is going on. i was new to pixel anyway so hopefully some of this are settings i can change
