Plugins update bug

I updated some of my plugins, but it’s not shown correctly. Look at this:

Random Posts 2.6.2.0 Deactivate
There is a new version of Random Posts available. View version 2.6.2.0

I am using the latest version, but the message is still there.
This is not unique:

Robots Meta 3.0.2 Deactivate
There is a new version of Robots Meta available. View version 3.0.11

It’c clear to me that 3.02 it’s newer than 3.011

So where’s the problem??
