[Zabbix 6.0] - Graph not displaying with range >3 days

[Alan.K]

Hi,

Following a topic I stumbled upon (This one)
I have the same issue, which is :

When I open some hosts' graphs, all values display properly as long as I don't have a time period longer than ~3 days. Sometimes less
All values display properly when I chose to display them as values instead of a graph
Displays "No values" on the graph even though they are present andd accessible
Not all items have this problem, but here I'm focused on Temperature and Uptime
All hosts who have these items can't display the graphs with a longer time range

My history & trend range for Temperature and Uptime are :
History : 180d
Trend : 365d

My overridden values :
History : 90d
Trend : 365d

I tried upgrading the files modified in this graph-related issue hoping it was a long time ago fix but no avail
I thought it was related to the difference between the French decimal separator (a comma as in 12,21) and the English one (a dot as in 12.21) but my temperature values are whole numbers

I attached some screenshots that may help : Some settings, a host with an item that doesn't have this problem, and an host which has it

Does anyone have a clue or the same issue ?

Thank you !
