Imported LiveLink csv animation has weird gaps every xxx frames?

Hello

We have taken about 10 sequences of live link capture but we end up with these errors in them >

Does any1 have any idea what/how to fix them? Or I have to manually move all the frames?

We captured them on iphone, exported, imported to engine as csv using the plugin for live link importing.
