Hello,
I just checked what the plugin was sending to the UPS platform and no matter what I do It's correctly sending the "negotiatedIndicator" which means that the issue is probably coming from your account which doesn't have access to negotiated rates, so the best solution will be to directly contact UPS about it.
Here is what we send to the UPS platform in your case :

As you see we are correctly sending it so feel free to also show them what we send to their platform so that if they find something or have some tips, we'll gladly adapt our code.
Thank you !
