Recorder Saves file with extension *.3Gp but adds another "." after extension

Recorder saves recorded message with and extension  nameofsong.3gp and sometimes as nameofsong.3gp. with a "." after 3gp

I am using Lenovo Laptop with Windows 10 with a Samsung Tablet SM-T230NU running Android Vers 4.4.2.
Here is the project Rec3GPFile.aia

Also Plays previously recorded audio file sometimes.

Thanks for your support.
Any reason why it does that?
