Runelk BT keyboard trackpad not working on iPad

I bought a runelk BT keyboard for my ipad from amazon. No issue whil connecting, and the keys work perfectly fine. However, there's a huge problem with the trackpad. It just does not work, and there's no any sign of cursor. But, when I turn on assistive touch and enable virtual trackpad, the hardware trackpad completely works. Since, turning the virutal trackpad on shows up the cursor, it is annoying to use the screen while there is the virtual trackpad interface on the screen itself. I am 99% sure that this is a software bug. If there's any help that I could get to use my runelk BT keyboard's trackpad, it'd be of great help. Thanks!!
