get-mcasfile doesn't filter on "Other" parameter

[silviews]

There is a problem with get-mcasfile with -Filetype Other or "0" . The filer is ignored & all results are returned.
My understanding is when passing 0 as int, returning false.

if ($Filetype)        {$filterSet += @{'fileType'=@{'eq'= ([int[]]($Filetype | ForEach-Object {$_ -as [int]}))}}}
if ($FiletypeNot)     {$filterSet += @{'fileType'=@{'neq'=([int[]]($FiletypeNot | ForEach-Object {$_ -as [int]}))}}}

    [Parameter(ParameterSetName='List', Mandatory=$false)]
    [ValidateNotNullOrEmpty()]
    [file_type[]]$Filetype,
