Missing CPU Graph

Hello,
im new on RouterOS and i am not sure about missing CPU graph under Tools > Graphing > Resource Graphs
I have only HDD and Memory and there is not posibility to add something else.
On login page there is link to CPU but shows error “ERROR: NO ACCESS!”

So I have something wrong or it’s a bug in 7.x?

I am also having problem with this

Yes. I have the exact same thing but in my case HDD and Memory is missing. This is still present in the latest version of RouterOS as the time of writing which is 7.5.
