Feet placement on pop up issue

Hey riders!
Lately, I noticed I'm having this issue at popping up, where when I jump, my feet are too close together towards the back of the board, so every time I have to do a small foot movement forward right after the pop up with the front foot (causing my board to move up awkwardly for a split second. I don't know why this is, but it is not ideal, throws me off and hinders me to do a bottom turn early enough to get down the line. It doesn't happen all the time. When I do a pop up on the sand, my feet are perfectly in place (front foot between hands, and feet little over shoulder width). Does anyone know what is causing this? Am I just not focusing enough on foot placement ? Or is popping up in the water a little harder than on the solid ground, thus do I need to jank it with a little more power ? Extra info: this happens mostly on smaller waves (avg Sydney conditions lets say). Hope anyone can help this half of a surfer out.
Info about me: I see myself as an intermediate, fit surfer being able to pop up swiftly, doing basic turns like cutties and carves and generating speed properly (not flapping but rail to rail) both backside and frontside.
Peace and thanks!
