Strange Graph Issues

I have a frustrating problem. When I load a dashboard some of the custom:mini-graph-card graphs only seem to how 10/11 days on my computer.

When I view via my phone the full range is there.

When I click on the entity name on the graph it takes me to the back end data for the entity and there is 2-3 months of data (from when I added it to home assistant).

I am not sure how to fix this though?
