Old poller remains shown in ui after switch to dispatcher service, delete button doesn't work

I switched to dispatcher service according to Dispatcher Service (RC) - LibreNMS Docs everything works well, but in the ui/pollers I can still see the old poller. There is a delete icon next to it, when pressing it I get confirmation prompt, press OK, page reloads and the old poller is still there. Just wondering whether this can cause any issues down the road. I have disabled the librenms cron file so the old poller is not running anymore.

the error is from integrating smokeping, the file gets regenerated each time smokeping updates and is owned by smokeping:smokeping, I do not think it affects anything.
