Contact your ISP why they are advertising /32 prefix instead of /24. As far as I know /24 is the minimum that should appear in global tables.

Try
 /ip route print where "address_you_ping_here" in dst-address
on your bgp router.
May be your ISP, for some reasons, dont have prefixes you are looking for.
All prefix lengths are legit on Full View, but most ISPs drop longer then 24.

So, this is a question for your ISP provider.
46.38.56.0/21 is perfectly visible on internet.
