CactiEZ problems with graph

[wizmatic]

Hello,

We have cacti running on an old server and I've decided to install Cactiez on a new server and add all of our devices. As such, they are both polling the same device.
However, I recognize there are inconsistencies in the graphs on the new cactiez and wondering if anyone ever encountered such an issue before.

The graph on top is the new cactiez server and the one below is the existing cacti. The polling period is the same as well as the display (5 minutes) for the graph.
