Custom content cause error with filter

Farcry 6.2.10/MySQL
When filtering a custom content item by title (that requires pagination) I 
get the error '"" cannot be converted to boolean' in objectadmin.cfm

I've resolved issue by changing line 1090 in the objectadmin.cfm:

<cfif structKeyExists(arguments.st, "bHasMultipleVersion") AND 
arguments.st.bHasMultipleVersion>
to
<cfif structKeyExists(arguments.st, "bHasMultipleVersion") AND 
val(arguments.st.bHasMultipleVersion)>

But perhaps someone know the reason for this error?

Cheers
Phil
