musescore import problems

Hi,
I have tried to import some scores and found that import software can't recognize time signatures like 7/8, 9/16 and so on. Please, see examples - source pdf and mscz - import result. There are also another errors - you can see them yourself.
I think that import can be very useful feature, but can we see in nearest future more correct results?
(if you need I can support you with more examples)
