payment integration settings

however by sheer luck.  When I click on the wand for the payment field it always takes me to the last settings page I was working with and does not show the gear at the top.  I’m concerned I won’t be able to get in if I need to change anything in the future.  I hit the save button, cancel out the settings, return to the builder, hit the wand again and it takes me back to where I was, no gear.  Even if I leave, work with a separate widget/field and come back, same thing.  Any suggestions?
Also, how can I change the size of the field where the amount is brought in from a user defined field?  It’s cutting it off and I can’t seem to find that setting.
Thank you, you’ve been very helpful.

It seems  you're stuck on the payment integration part. You need to input your credentials and click continue to be able to view the payment settings.

Here is a sample screenshot using PayPal:

May we know the payment integration you're using?

Can you please share to us the form you're working on?

Thank you.
