The roses are showing classic symptoms of weedkiller damage, probably glyphosate, due to carryovwer in the sprayer. These are probably the ones sprayed first.

They normally grow out but it can take two years. Do not prune.

It is always wise to have two sprayers, one for weedkillers and one for any thing else.
