Good morning, I would like to point out that I don't use the software often. Today I need to do some calculations and I discovered that both with a new project and by opening an old project, the software changes the norm and therefore the usage profile to "5.1 DIALux Preset" and "5.1.4 Standard..." and I have no way to change it. Is this a limitation created to encourage the subscription or do I have some problem? All the projects I open are modified with this profile. Thanks
