the problem with the creation of groove and quantize

incorrect work of the function in the hitpoints tab (to create a groove, create markers, create events). When using the function to create the groove, there is a blank window pane quantization does not read the groove defines duration as 0 bar. It happens all the time, the function only works the first time if I want to create a groove on the other of the loop there is this bug. Markers are not created at all events through time

the same here, when i create a groove quantize from an audio event that its at bar 10 (for example) the quantize is done at bar 0, really useless…
