BGP advertisments don’t show up in /ip routes (unless the ip routes you pasted is from the remote router - it’s not clear the way you pasted these - no hostname is shown)

You can advertise stuff and not have them in your routing table. And you can have stuff in your routing table that are not advertised to BGP.

I believe the culprit is that you are using a different routing-table for the BGP instance.
I remember I saw this bug last year while trying to implement a BGP version of the Blacklist Filter script by IntrusDave
http://forum.mikrotik.com/t/blacklist-filter-update-script/89817/84

It’s mostly cosmetic (since it does advertise the prefixes) but it sucks since you can’t do proper troubleshooting.

I guess you can submit a bug report to support@mikrotik.com

I agree: using separate routing table for BGP instance works fine, but “advertisements print” does not.
You need to debug without that. E.g. look at the other side.
