ATF Form's Showing "X" in boxes where Signatures Are Required

When creating your ATF Paperwork digitally, the ATF paperwork can be picky.  You need to use Adobe Acrobat products to ensure that the information is populated throughout the form. That is why we created the ATF Form Generators that takes the effort out of it.  Our ATF Form generators create the forms for you without the use of the Adobe Acrobat products.  Whether you use our ATF Form Generators or Adobe Acrobat products to create your ATF Form paperwork, you might see an "X" through the signature fields.  Why is this?  This only seems to happen on Apple related devices and operating systems.  Meaning when you preview the ATF Form on an Apple iPhone, iPad, or Apple OS using "Quick Look" the "X" will show in the signature fields.  However, when you view the ATF Form with Apple "Preview" or an Abode Acrobat product the "X"'s will not be present.  Below you can see the examples of the Apple products vs the Adobe products rendering of the ATF Paperwork.
