ColdFusion Builder and Eclipse Quick Diff

I have installed ColdFusion builder (CFBuilder) (v3.2.1) as Eclipse (v4.17) plugin and I see that the Quick Diff functionality does not work with CFML Multi Page Editor.

I am using the Code Assist Dictionary Version as ColdFusion 2018.

I am not sure if this a bug in the CFBuilder or I am missing something here?
