Unable to Add More Than 3 Gift Designations in Single Gift Entry

Hi Experts, 

I am trying to create a Gift Transaction and allocate my gift to 12 Gift Designation records using the New Gift Entry button. However, when I try to enter the gift, the form only allows me to add 3 rows.

Please find the attached screenshot for reference.  

I am not sure if this is a limitation in the Single Gift Entry Form

I was also unable to find any information about this in the help articles.

Can anyone please help me get better clarity on this?
