RRDTool 1.5 Error and Installed RRDTool ver. 1.6

[jamthejame]

I'm new to Catci and in the process of installing and noticed in /system utilities/technical support the following:

"Error: Installed RRDTool version does not match configured version. Please visit the 'Configuration Settings" and select the correct RRDTool Utility Version"

Now, in configuration files i only have RRDTool vers from 1.0.x to 1.5.x
Meanwhile, the installed version by running RRDTool in the terminal is ver. 1.6.0...

It this normal? if not how should i go about resolving it?
