When I delete your section and create new, everything was fine.
I tried to make this type of bug on my test website, but I can't simulate it. If I fill there wrong data (seats) and save, then correct data and re-save... Everything works fine.

ok i´m going to try it, but i see a problem, i cant select seat, if you try to select a seat its not change color and i can´t reserve the select seat.

try

Thanks again

I am not sure what browser do you use (in FF you will have problem to find any seat). But main problem is, that you have not selected any seat image. Upload there image with 10x10 px.

That image need to have transparent field, where will be shown selected background color. If image has not transparent background then color for selected item will be not visible. Image need to have also some visible borders, so you will be able to find seat and click it.

You can use gif or png image formats.

ok now i´m using a png file 10x10 pixel and select seats perfectly.

but in the 4 row something is wrong:

i put 11 seats in sections name, in the window of select seats apear 13 seats in the first block of 4 row

maybe exist a problem with conversion since 4 row

check it please
