App inventor is taking photos from other projectors and putting them in my new project.
I just upload 5 photos at media and when i press random it takes photos from other projects.
Hello Alvaro,
Without relevant information it is impossible to help you. Please screenshot relevant blocks that you believe cause the issue or export your AIA here.
Clear TinyDB and try again
It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.

Is this happening in built apps, or just in the Companion?
The Companion is a bit of a garbage can, collecting leftovers from other projects.
