Unusually slow in adding/removing a product bundle row in the form

[arjan-coolminds]

Sylius 2.0.12, bundle version 3.0.1

Clicking on Add (or remove) a product bundle field takes between 5 and 20 sec. We have currently 4893 products, so not that much. (We have no bundles yet, this is staging phase for our customer)

Is there anything we can do to speed up this action?
