Call Recodings do not showing according date/time of creating

[Tomss]

Hello, I use Redmi Note 4x and few days ago I moved call recordings from directory (MIUI - Recorder - Call Records) to my PC because I was running out of memory in my smartphone. Today, I wanted restore recordings by copying recordings from PC HDD to original directory to smartphone. When I checked call recordings, I see all records as recorded during April. I mean that call recorder does not displaying call recordings according date and time it was created. All recordings are showing like created in April. Any idea how fix this issue please ? Thank you.
