Problem: one grid will not deploy changes to deployment enviroment

I have a strange problem with sc9 deployment. works fine but there is one grid that i changed in the production environment and these changes will not deploy.

i changed an application link
I changed a lookup (default value)

those changes work fine in development, in deployment they do not appaer.

  • i deleted the folder with ftp and upload again (old version upload , not with the latest changes)
  • tried different types of deployment
  • cleared cache, use different brwosers

still the changes are not madeā€¦ any suggestions
