Problem with combination of EAP Correction and Slice Assembly

I downloaded the following two files
S1A_IW_SLC__1SDV_20150112T165544_20150112T165611_004141_00504C_4DE2.zip

If I try EAP Correction after Slice Assembly I get the following error report:

If I try first EAP Correction and then Slice Assembly I receive
Error: [NodeId: SliceAssembly] String Index out of Range: 48

Help would be appreciated!

I meanwhile found what probably caused the error in case of first doing EAP Correction and afterwards slice assembly. Both EAP corrected files had the same name (but were necessary in different folders). After redoing EAP correction and attaching only the suggested ending to the file names slice assembly worked.

thank you for reporting your solution.
