The reason you're not able to split your TIF image into 4 channels is that your exported it as an RGB tif, which only has 3 channels- R,G, and B. You'd need to export it in a different way that preserves the channels to extract all 4.
Extracting the metadata in the LIF in CellProfiler worked fine for me though- see first figure below. Make sure you hit first the "Updata metadata" button under "Extract metadata from -> All images", then the "Update" button at the bottom in the pane displaying what images have been found.
It seems like some of your series only have 3 channels, while most have 4; this is likely going to cause CellProfiler some problems if you're trying to apply a 4 channel analysis to all of your series. You may want to do something that limits it only to series which have 4 channels explicitly in NamesAndTypes- see second figure below.
