Ascend g6 rooted, internal memory not visible

[dellaera]

Hi. I have rooted my ascend g6 u10 b360 with kingroot, but I didn't see internal memory anymore. I unrooted it but the problem didn't go away.
If I set the external sd memory as default, I see internal's and external's memory files, but if I set the internal one as default, I don't see again its files.
Can someone help me?
Thanks.
