[PyGame] Sprites just randomly appear and dissapear in my pygame.sprite.GoupeSingle

trueShadoWrr

I am programming my first "real" game in pygame and now I ran into a Problem.

So I am trying to program the mainmenu of a game and it is already working that if I press the quit button, it quits and if I press the start button, it goes right into the game. But if i want to press the option button, my program should go into the options and for that I need to remove the start, the quit and the options sprite out of the group, so it can draw on the screen. After that I want to paint the screen black so the buttons dissapear and also I want to add a knew button at the bottom which says "back to menu..

So my problem is, that when I kill the sprites, only the option sprite gets killed, the other ones are just randomly getting added to the group again and I have no clue why. So in this case, when I want to go into the options, only the options button dissapears.

I have tried following the path, after the sprites should get killed but I did not find anything. I have also tried printing the groups before they get killed, after they got killed and in a while True loop to see where the problem is.

update_Hauptmenu() calls pytame.display.update(), but it does nothing to "erase" sprites that have been removed. There is no erasing in Pygame, so if you want to erase something from the screen you have to paint over it, then draw all your sprites, and finally call display update() or flip().

I have tried following the path, after the sprites should get killed but I did not find anything. I have also tried printing the groups before they get killed, after they got killed and in a while True loop to see where the problem is.
