Xiao 2040 -pins do not go fully into the socket of the expansion board

HI,

I bought Xiao 2040 and the expansion board:

However I cannot pull down the Xiao 2040 pins into the socket. There are 4 connectors of some kind which doesn’t allows that. Attached is a picture for your reference. Can someone tell me how this can be done? I am pretty new to micro controllers.
