Weird behavior when gravity forms throws error

Dear support team

First of all, appreciate your great works for developing “Sliced Invoices” and “Sliced Invoices + Gravity Forms” Plugins.

I have two issues with the combination of the aboved mentioned plugins together with Gravity Forms:

1. When I create multi-step form and put the list element in the second page (or pages other than the first page that contains fields of customer details), the list items won’t change to select items.
I found the same issue mentioned by other user here: https://ww.wp.xz.cn/support/topic/multipage-navigation/ , but couldn’t find your solution “It should work with multi-page forms, but the line items do have to be setup in a particular format”, could you please elaborate on the solution?

2. When the user doesn’t fill any of required fields and gravity forms displays an error message to them that it is required or any other defined errors, again the list items changes back from selectable list to a normal list item. The user should manually refresh the page in order to see the correct version of list items. (Also checked on your demo site https://slicedinvoices.com/demo/quote-request-gravity-forms/ and it has the same issue – Screenshot attached)

Also I have a question about one feature:
When I define line items in Sliced Inovices, the first column is Qty, is there any possibility or code tweaks that I can implement to restrict user to enter a minumium numer for that field? e.g. I define something like this:
24 | Sending Emails | 2 | Sending marketing emails
I want to have restriction on Qty column, I mean it doesn’t let user to enter any number less than 24 or so.

I use the latest version of WordPress, Gravity Forms, Sliced Invoices, and Sliced Invoices + Gravity Forms.
