Hi
I checked the local plugin and I think I found (perhaps) a solution (to be verified).
I changed line 319 in /opt/omd/sites//lib/python3/cmk/base/plugins/agent_based/local.py
from
if local_result.cached.elapsed_lifetime_percent > 100:
to
if local_result.cached.elapsed_lifetime_percent > 200:
and all services seems to be up to date.
For a real fix this should perhaps not use 200% as a threshold but a combination of cache time, scheduled check time and a little bit of time buffer.
e.g. max(cache_time, scheduled check interval) * 1,1
