I've thousands of Word 2010 documents, whenever I'm saving any of the document in MS Word 2016 Format; while saving if not checking the "maintain Compatibility" checkbox, the whole layout is changed.
if someone can help me out to maintain the layout. I've attached two files/images. I need to have the same layout of MS Word2010 in word2016 .


I think its just playing with tabs, am very much confused, not able to regain that layout of ____ ____. after paragraph mark.
2016Format (lost the layout, see TABS position)

2010 Original Format
Thanks for help.
