Go to e.g. https://mzl.la/2ZqFJHV and then in the selector sentence at the top, try changing "Firefox Desktop" to "Firefox Mobile".
Expected: the histogram goes away, or gives you some indication that this probe is not recorded on mobile.
Actual: histogram remains pretty much where it is, showing the desktop numbers.
The problem is more obvious if you go to the mobile stats for a different probe, e.g. https://mzl.la/2ZotGL6 and then switch the probe name to FX_TAB_SWITCH_COMPOSITE_E10S_MS - it will keep showing the old probe data.
