I am developing an application to help children with functional diversity learn to read and write.
In the first activity of the app, children have to pop the bubbles of the letter indicated, for example, pop all the bubbles containing the letter "A". I have two problems, the first one is that I am not able to hide the bubbles that I have declared in the .kv, as you can see in the image, the bubble "Z" appears immobile in the lower left corner and I think that bubble appears because it is the last one that I have declared in the .kv.
The other problem is that I am not able to have more than one bubble with the same letter.
