Product configurator

Hi,
In the product configurator, when we have an option that becomes mandatory from an answer and that same answer, I change it to another that has no obligation to answer, the configurator is lost when recording the data.

He follows.
In the image, the SEED DISTRIBUTOR - CONVENTIONAL is mandatory to inform the parameter ASSEMBLY FOR: SOJA OR CORN.

In the second image, I change the SEED DISTRIBUTOR option to TITANIUM, which does not require the MOUNT parameter to: SOJA OR CORN.

When I do this operation and save the data, when doing the work order, the option ASSEMBLE TO: SOJA OR CORN is taken to the OT even though it is the other choice.
How do I clear settings without closing the screen and starting setup again.

Thanks

João Antonio
