which version of MIGX are you talking about? The one from repo? Or the latest one from github?
Do you have a screenshot?
what is your configuration?
You don't need to create a TV for each field. You can reuse TVs for more than on field.
And you don't need to create any TV, if not one with special configurations.
In most cases you can use inputTVtype
{"field":"myCheckbox","inputTVtype":"checkbox","inputOptionValues":"optionA||optionB"}
you can also use the MIGX - Configurator-CMP and create configurations there.
then you would just fill the configs - field of the MIGX-TV with the name of your configuration.
