Do I have the wrong board?

Hi all,
I have a 7 foot Superfish and am having issues popping up on it and was fine before on some 8 foot boards and thought this board would be a good transition board. Do you think this board would be significantly harder to pop up on or should I go back on the 8 footer for a while and come back to this board later. I'm trying to figure out if this is just a learning curve issue or if the board is the problem. It's really wide and thick so not really an actual shortboard.
I'll do different things but ultimately im having difficulties getting my front foot forward and underneath me quick enough and I'll go to my knee etc... I think the larger board allowed me to have room for error in the pop up but this board needs more precision and that is part of the problem. Any opinions about whether I should continue with this board until I get over this learning bump in the road or move to a different board? And will i eventually get over this and is this a normal problem for more advanced beginner surfers when they go to a new board?
