Blocs 2.6 is driving crazy. 2 pages became the same! why!?

I made home page…fine…I selected Add new page…fine…then I made the product page…I checked in preview…ok fine…two different pages…fine…
I keep doing my stuff…now…all of the sudden the home page has become the product page design…!!! how is that possible!? i just lost the home page design!
What’s going on?

Do you have any content in the top global area?

No, everything is in the right place

Did you duplicate a page or use a page template? Somthing is not right (obviously), but I’m not sure what. Do all pages still exits in project file?

You’re using Blocs v2 right?

alright…i don’t how but all back to normal. this is weird
