New-UDTable with Search not getting selecteditems

Product: PowerShell Universal
Version: 1.4.6

When i use New-Udtable

                            New-UDTable -Data $Cache:Deployments -Columns $Columns -Id 'Tbl_CustomerInformation'  -ShowSearch -ShowSelection -Dense -Paging -PageSize 20 -Export -OnRowSelection {
                                $session:SelectedItems = Get-UDElement -Id "Tbl_CustomerInformation"
                                Sync-UDElement -Id 'dynamicSelect'

and then use $Session:selecteditems it gets all the selected items ok. however I have a search option enabled on one of the columns. if I search and select multiple items only the last selected item is in the $session:SelectedItems.selectedRows variable.

this issue seems to only happen if I use the search functionality. any help would be much appreciated
