Graphs in Zabbix server 5.0 are experiencing gaps using agent 5.0.1 which is automaticaly installing from official Ubuntu 18.04 repo. We have multiply Ubuntu 18.04 servers with Zabbix Agent2 5.0.0 working well, but 5.0.1 is having this issue.

Steps to reproduce:

1. installing agent2 with official steps
   sudo wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1+$(lsb_release -sc)_all.deb
   sudo dpkg -i zabbix-release_5.0-1+$(lsb_release -sc)_all.deb
   sudo apt update
   sudo apt -y install zabbix-agent2
2. configuring zabbix agent2 same way as on other servers
3. adding agent to server same way as others

Result:
See screenshot...

Expected:
Graphs without gaps
