Missing 95th line and data when using API get_bill_graph

Hi,

I am trying to use API to get the billing graph using this: https://librenms.org/api/v0/bills/1/graphs/bits

I am OK to get the graph data, then convert from base64 to png. All perfect!

But the issue is that the png seems like doesn’t have the 95th data and the red line on the graph as well.

This is the librenms version info:

====================================

Any ideas about this?
Thanks!
