Asterisk not showing in Mandatory Fields in Guest Checkout

[Plain Me]

Prestashop version 1.6.0.14

I've been having lots of problems with Guest Checkout, and eventually sorted the problem by changing some code which has now included the Home number field as well as Mobile Number fields? Problems I now have is that the two fields do not show an Asterisk indicating mandatory fields which is creating problems for customers. The original problem was that guest checkout did not work because it wanted a mobile number entering in the field, but even adding this the screen crashed and checkout did not work. I'm seriously thinking about changing my e-commerce shop! I never seem able to get the support, so please someone prove me wrong!
