It is indeed likely a language issue, but the language issue is with the 3rd party items. We cannot diagnose issues with 3rd party items. If you can determine what the issue is with your 3rd party developer and it appears to be something in core they can provide more details on, we can certainly then take a look at that.
I can fully appreciate that you have stated it has been dragging on weeks here, but it does need to be noted this topic was started on Sunday. Also, we have asked if you can go back to the developers of those 3rd party items on more than one occasion. I have flagged this topic so that a developer can review, but it is extremely difficult to assist if you're unwilling to follow the advice we are giving.
