Hi @Mattianiskasaar ,
Thank you for the additional information. When an SD card is formatted as internal storage, it becomes part of the device's main storage, and the system manages it as such. This means that files are not truly moved between the internal storage and the SD card; instead, they are managed as a single storage pool.
The behavior you're experiencing, where the file appears to be in both locations and deleting it from one location removes it from both, is consistent with this setup. The small SD card icon indicates that the file is stored on the SD card portion of the internal storage.
To avoid this issue, you might consider reformatting the SD card as portable storage if you want to manage files separately between the internal storage and the SD card. You can find more information on how to set up your SD card as portable storage in this Google support article.
If you need further assistance, feel free to ask.
Best regards,
