PPoE clients connect but not showing on correct interface

I’ve run into an odd issue on my MikroTik PPPoE server and would appreciate any thoughts

When some PPPoE clients connect they don’t appear under the expected interface (the access interface where the PPPoE server is configured) (other clients are connecting fine on different interfaces)

They sometimes show “floating” at the top of the list in winbox

When I click on the session, there’s no Remote Address shown.

Yet the IP shows if i go to ppp > active connections

See below

Downgrade to version 7.19.6

im on v 7.19.3
should i upgrade to 7.19.6 ?
