CPU and Memory count of added devices

I am currently testing following version of Librenms in centos 7 machine with rrdcaching enabled.

LibreNMS | 1.70.1-6-g9ccb707
PHP | 7.4.13
Python | 3.6.8
MySQL | 10.4.17-MariaDB
RRDTool | 1.7.0

Everything is working fine. But the issue is, whenever I increase or decrease CPU or Memory of added devices. Those changes does not reflect on LibreNMS interface even though polling is working fine.

I have to manually rediscover the added device to reflect those changes.

Is this normal behavior of LibreNMS or do I have to change anything?
