Wrong line spacing for font in Adobe Acrobat

I opened up a document I edited in Acrobat a few months ago and wanted to copy an exact text from this document to a new one. Basically copying a text from document A to document B.

In document A, the fonts' line spacing is set as 0,87. 

When I copy this text and paste it into document B the line spacing is 1. When I try to put the same 0,87 an error box shows up saying "value must be between 1 and 5"

How can I fix this issue?

Could it be the new update?

Please help me :(((
