After Effects import doesn't set the frame length for last frame correctly

[LarsJandel]

Exported from Krita, imported into AE, the last frame doesn't get a correct frame length, gets shorten to none, does not display. So the precomp with the images is also too short.
In the example with three frames, please look at the layer shown at the bottom right.
The comps should be one frame longer and the last frame should have a proper length go one frame.

Thanks
