Error when trying to create Bundled Product

When trying to add a new Bundled Product in admin I get this error:

The “componentType” configuration parameter is required for the
“tier_price” component.

I’ve logged the data which contains this:

[tier_price] => Array
                                                        (
                                                            [children] => 
                                                        )

But in another install it should return this:

[tier_price] => Array
                                                        (
                                                            [arguments] => Array
                                                                (

                                                                        (

                                                                                            [text:MagentoFrameworkPhrase:private] => Customer Group Price
                                                                                            [arguments:MagentoFrameworkPhrase:private] => Array

                                                                                        )

                                                                                    [code] => tier_price
                                                                                    [source] => advanced-pricing
                                                                                    [scopeLabel] => 
                                                                                    [globalScope] => 
                                                                                    [sortOrder] => 30
                                                                                    [componentType] => dynamicRows

Everything appears to be fine in the attribute set and is fine for simple/configurable products.
Any ideas what might be going on?
