I'm having an ongoing problem with my OLX forms loading in correctly. Essentially some percent of users click a link on our website to a form page and get a form that loads all possible fields and doesn't respect any of the code presents (no preselect payment option or payment amount). The forms show a dozen unused fields for addresses including those from countries we don't have selected and then nothing can be entered in the form. It looks like this:

I have been through two separate long exchanges with Support and they've determined that all my RE settings are correct, that I haven't altered the code blocks for the forms, and that we're are putting the code blocks on our webpages correctly. They also identified a potential conflict with the OLX newsletter sign-up widget in the footer on our pages, but we've removed that across the whole site and it hasn't helped the problem. Support said it's basically my problem and something on our website causing it, but that's been very hard for me to troubleshoot since the problem doesn't happen consistently and I can only some times recreate it.
Now I'm hoping to find anyone else who had a similar problem and knows a solution or just has any suggestions. The RENXT are not an option for us because they don't provide the necessary fields for the way we use donation forms.
