I've reported this bug before (years ago) and nothing's been done to fix it:
If I make a mogrt using AE sliders and import it into PPro, none of the sliders' values show as anything other than integers; eg. if I've set the "start time" of something to "0.5" in the Properties Panel, it shows as "1". Even when I click on it to edit the value, it still shows as "1" even though PPro is in fact seeing it as the correct "0.5". If I change it to "8.15", it shows as "8". I think in ye olden dayes of mogrts, even though PPro showed fractional values as integers, if I clicked on the value to edit it, PPro would show the correct fractional value. But not any more. I'm on PPro Beta 24.6.0x75, and the latest, corresponding version of AE Beta.
This is a really annoying problem that's been around for a LONG time!
