Internal SD card storage


I internalized the SD card on my Moto Z play phone a few months ago. Now, I’m getting "running out of storage* messages.
If I go to storage in “settings”, it’s showing 49.61 out of 64 available gigabytes of storage used.
It shows 31.73 of 32 available gigabytes used in internal storage.
It shows 17.68 of 32 available gigabytes used on the SD card.
I’m under the impression that when the SD card is an internalized there is no distinction between internal storage and the SD card.
If I go to my file storage app, it shows 26 GB out of 26 GB used on internal storage. It shows the SD card as being unavailable.
Why the discrepancies?
