Expiration notice mails

i become Mails thats my certificate will expire in 6 days (on 03 Mar 16 21:45 +0000). But on my Server i run a Crown Job thats monthly renew the Certificate. When i check my Site on ssllabs.com i found this Information

Valid from Sun, 31 Jan 2016 22:01:00 UTC
Valid until Sat, 30 Apr 2016 22:01:00 UTC (expires in 2 months and 1 day)

My question is now whats wrong? and what can i believe?

It’s a known issue you still get them even if the cert has been renewed.
