Variety is the spice of life as they say, and deer, rabbit and other critters always seem to be interested in trying newly planted material, even the varieties that are not usually browsed.
As long as the plant roots are not disrupted, this looks like a pruning for you. It can have some advantages to reduce flowering for the first year as roots can get better established. Monarda and milkweed in particular will spread like crazy once established as you surely know.
You can protect any new plants until they are established with repellent sprays, fencing or covering with floating row cover ( https://extension.umd.edu/resource/floating-row-cover ) or perhaps arches of wire covered by open netting. Fwiw, deer tend to bite and tear while sharp rabbit teeth make a cleaner cut.
Apparently once flowers begin to bloom they may try again. If you have high pressure/presence of wildlife, you may need to spray again at that time. Here is a page on deer repellent products: https://extension.umd.edu/resource/using-commercial-deer-repellents-manage-deer-browsing-landscape
