S7 edge G953F 2 sim toolkits 2 imei

[BIGRED1682]

Hi guys,
I'm here coz I need your help and advice.
I have an s7 edge and it shows 2 sim toolkits in system apps.
Its not a duel sim phone!
I've tried a few things to find out y but no joy.
Also I downloaded an app called my sim toolkit and that shows imei slot 1 and imei slot 2 and they both show the same imei
When I do *#8080# it says invalid MMI
Whenever I try a code that starts trying to run the USSD code it always says invalid MMI
I have also just added some screen shots
Hope you guys can help

The "second SIM card slot" is for the SD card in the F model (the FD has 2 SIM slots). The nomenclature has come out a bit strange (maybe due to Korean being translated to English).
