Lost the sim toggle feature

Updated my phone (H961N dual SIM) using LGUP, from V10B (SEA-XX) to V10c (GLOBAL???) variant.
I realized that lost the sim toggle feature. (SIM switch button on Home Touch Buttons bar at the bottom of the display is not working / not switch between SIM cards).
I did factory restore, and reinstallation (LG Bridge).
The problem is not solved.

Anyone know the solution?
