Missing values in pdf fillable forms

I am using Adobe to create some pdf's with fillable forms. Then I use node.js application to fill the pdf files and also merge them into a single one. When I open the final PDF in browsers and other PDF readers it displays fine. All the forms are displayed correctly with filled values. But when I open the same in Adobe Reader a few forms are coming as blank. Why it's happening like that? Please provide me with a way to fix it.
