NAV 2017 CU7 Vendor page crashes with spaces in vendor number

Hi,
Installation is just lifted from 2017 CU 0 to 2017 CU7.
Some vendors exist with spaces in number field, like "+47 123456" etc.
When vendor card is opened on a vendor with spaces, the client crashes.
Same happens in list page, if vendor with spaces is highlighted, so Sum box calculates the specific vendor.

This was not a problem before CU7. Anyone know of a possible fix to this?

Thanks.
