Bizzare Slider Object

[#1]

I have a simple bar chart showing sales by lead source by month. I created a Listbox called "Month", based on the field of the same name, which lets the users select the months to inspect. Then, I decided to get fancy, and add a slider object to the same page, also based on the field "Month". The object shows up fine, everything is in the right order, and it works fine, except for one tiny thing: the names "Apr" and "Sep" do NOT show up in the slider object UNLESS the user is actively selecting that month. For example, if the current month selected is "Mar", and the user stretches the slider, the box above the slider shows "Min: Mar Max: Apr", and the bar chart updates perfectly. But as soon as the user releases the mouse button on the slider, the min/max box disappears, and the name "Apr" again doesn't show up in the slider box. Meanwhile, in the original "Month" listbox, both Mar and Apr show as selected, and both months appear in the bar chart. This only happens for the months April and September - all the other months show perfectly all the time. I'm stumped!!

Found a workaround - went into properties, and selected "Use Custom Scale", set major units to "1", and everything showed up fine. Still bizarre, though.
