Why conditionnal compilation symbols are the same

I noticed that there’s several occurence of MF_FRAMEWORK_VERSION_V4_3 in my conditionnal compilation symbols even if I removed duplicate few days ago. Is it normal? is there any explanation?

@ leforban - I have noticed the same. When I erase second one then it is there again after some time…

it does not seem to be a problem but just for the sake of understanding I would like to know
