HELP!

Feeling very deflated right now. I have really struggled with this front wall. The number of times I almost gave up on it and ordered a new one....Anyway, I'm still struggling. It's not wanting to close properly - despite me having measured, re-measured, fiddled, footled and test-fitted. The second story seems to fit beautifully but the bottom keeps catching. I adjust, think it should work and then have to adjust something different next time I try it. I am considering pulling all the stand out panelling completely off the inside of the bottom story and making the panelling completely flat instead. I can't do this with the second story as it's well and truly a part of the wall - but I could quite easily do it to the bottom. As it now stands, I'm really not liking that wall - it is certainly not up to the standard of the rest of the build. So....question....your opinion - should I pull off the 3D panels and create flat ones?
