Lens not showing node memory usage, CPU and disk works fine (on Raspberry Pi cluster)

[MasterWayZ]

Describe the bug
The cluster is four Raspberry Pi 5 running Debian 64-bit lite.
I let Lens install prometheus and node-exporter, and for the nodes tab I see usage except on the memory row (see screenshot 1). The overall view (screenshot 2) works fine.

To Reproduce
Steps to reproduce the behavior:

1. Go to the nodes tab

Expected behavior
The memory "bar" being colored.

Screenshots
Screenshot 1a (no memory usage showing):

Screenshot 1b (after clicking on a node):

Screenshot 2 (overall dashboard looking fine):

Environment (please complete the following information):

• Lens Version: 2024.1.170738-latest
• OS: [e.g. OSX] macOS 14.2.1 (M2)
• Installation method (e.g. snap or AppImage in Linux): DMG file

Logs:
When you run the application executable from command line you will see some logging output. Please paste them here:

Kubeconfig:
Quite often the problems are caused by malformed kubeconfig which the application tries to load. Please share your kubeconfig, remember to remove any secret and sensitive information.

Additional context
I hope the screenshots explain enough of the issue.
I have tried running a stress test to make a pod use around 4GB of memory, but it still didn't show up on the memory bar.
