Copying midi through lanes question

Not sure if this is an issue with cubase 10.5 . When copying midi from lanes sometimes only certain parts are copied and others replaced. For example lane 1 was hi hats, lane 2 claps, lane 3 kicks etc. When i drag the midi to copy or alt drag only lane 1 and 3 will copy over or any random combination. I have tried many midi recording settings and its only when using lanes that this problem occurs. Does anyone have a workaround? I attached a picture for visualization.
