Missing text when combing documents and requesting e-signature

Of course! That makes sense that you need additional infomation. The contract was originally created in Word. We then brought it into Acrobat to add the form fields. 

Here are the steps that are taken:

1. The designer fills out all the information in the contract.
2. She then signs the document with the fountain pen
3. She then has to flattened the document (Microsoft Print to PDF) so that she can combine it with other documents 
4. Once flattended she opens the flat version of the contract, other documents and scans that need to be combined. 
5. All documents are combined. All the information is there.
6.  The designer selects one of the 3 options to request an e-signature (E-sign, Request e-signtures or Fill & Sign)
7.  Then enter the email of the client and proceed to the steps to place where the clients needs to sign
8. All the information is there for a second then blicks and certain texts and/or the designer signature disappears.

I tested it without combining it with other documnet and it's doing the same thing.

I've attached a blank version, one that has been signed/certified and the Flat version.

thank you for your assistance.
