Question about the info tooltip for ZIPs

I´ve set a bunch of tooltip items in the file type group "Archives", like

{name}
{createddate}
{sizeauto}
{filecounttotal}
{dircounttotal}
{desc}
{zip:compcrc}
{zip:compratio}

but only the first three seem to work. I´ve looked through many other items, that might affect the result, like
the ZIP file type, folders, all files & folders etc., but can´t find no explanation. What could i have overlooked?

{zip:compcrc} and {zip:compratio} are for items within zips, not for zips archives as a whole, so I wouldn't expect them to work.

The others should work as far as I know.

It might be worth removing {zip:compcrc} and {zip:compratio} in case they are causing a problem. Failing that, stuff like checking that if you put some text (e.g. "Hello") into the infotip then it does appear; if it doesn't it means you must be editing the wrong filetype/group.
