Some Questions on ZSTD Compressor and Educational Decompressor

Hi,
I would like to know what are the differences between actual decompressor and educational decompressor.
Few things i noticed are :
Educational decoder decodes literal streams one after the other.
No Checksum checking enabled

I have a zstd compressed file, with literals are compressed in 4 streams. Educational decoder decodes it properly, actual application decodes it , but data is wrong. i have taken the debug dumps and checked them, sequences are matching , but there is no literal related debug points as such . i think something is going wrong in the 4 stream decoding section. please help me with some debug points ?
