SDK Latest version does not allow changing of properties

I can’t modify a project before the update: for example I change the position of a builder, I remove the solid line from a taxiway, when I do the BUILD PACKAGE I get a RED error (packagebuildlog_G AddKey wrong key: PREPARE) that I didn’t have before and doing export of the project, then I find myself that has not made any changes.
all the things I did before were successful updating the exported mod, now the project does not want to take into account the changes.
have the roots of the package directories changed? I am speechless.
Thanks for your help
