Why are files saved on my external portable storage count in internal storage?

[jsnodin]

Hi all,

I have a weird one that I can't find the answer for.

I have a Lenovo P2a42, 32GB, Android 6.0 OS, with a 64GB external Samsung SD card.

I have formatted the SD card as an external SD card and set my apps where I download content - mostly Google Play Music and Netflix - to save it to external.

When viewing my files (using ES File Explorer) I can locate these data easily in the external storage folders. e.g. see image below from External > Android, Data > Play Music >.

However, when I view Android data storage in Settings > Storage & USB, these external files are counted incorrectly in the internal storage. See screenshot below.

Anyone else had this problem? Can anyone offer a solution?

Thanks a lot in advance if anyone can help.
Josh.
