Text box spacing changes while new row added in configurable list

We have a configurable list that everytime you add a line it pushes the text boxes further and further off the right of the screen.  We could desperately use some help. 

Thank you so much,

Frank

Hello Frank,

As I check your JotForm, I was able to see that the list is working fine at my end.

Could you let us know the browser and OS that you are using? It may be also an issue with screen resolution. Please provide us with little more information of the environment that you are using so that we shall try to replicate the issue and provide you with necessary assistance.

Thanks.

We have tested it in internet explorer, and firefox on windows 7 and 8.1.  We have also tested it on safari, firefox on yosemite

I have also tested it in chrome on Windows 7

I have tested this on IE8 on Windows 7

and tested on FireFox on Windows XP:

As you can see both of them show the widget working properly.

I have also tried to remove some values, pressing enter in the fields and adding removing them randomly, but none of this resulted in the same issue as what you have mentioned above.

Could you please tell us if there are any specific steps that need to be taken and if the form is used directly over the link you have given or is it embedded on some page?

Going back to the screenshots it looks as if the images were taken on some website or in our Form Builder - not when viewed directly and no widget should be used while within Form Builder as it would either not work properly or possible cause issues.
