Auto-Fill not correctly adding products to a contract OOS

Hi, we are using V15.4

We have found an issue when creating a Contract or Contract Quotation, when adding products to the Obj. of Services (OOS).  In V15, once you start typing in a field, the auto-fill feature offers you matching products and you can select what you want from the list and it seems to add the product BUT we have found that it does not really add it properly, only looks like it did.  To properly add the product you MUST also click the elipsis (...) and then select it in the pop-up.

If you don’t select it properly, you only find out when you run the PM Batch Scheduler and you find that all of the products not added properly, do not get added to the Service Orders.

I think it will be necessary for me to open a support request for this but my question for now is: Is there any way to turn off the auto-fill, to stop it suggesting matching choices?  Then we can avoid the issue until fixed.

If so, can this be set per module or would be a global switch off?  Is it controlled in Alliance or is a web browser setting?

Thanks

Chris
