If there are no descriptors, the "All files" is automatically appened onto the end of the filter. The solution is to add descriptors to your filter string array, e.g.:

[FileName, FilePath]  = uigetfile(["*.mat","ABC";"*.xls","DEF";"*.xlsx","GHI"])

Of course you should change the descriptors to suit those file extensions.
