It looks like you used Append to import the collection into your scene. And in the Append options "Instance Collection" was enabled. You can see it from the orange collection symbol in the Outliner. This is just an empty which instances the collection.

And this means you just have a linked duplicate to the original collection in your scene which can only be changed as a whole, but only transformations like moving, rotating, scaling. You cannot edit individual objects or meshes or delete individual parts, only the collection altogether.

To be able to manipulate individual objects you have to convert the instance into real objects. You can do this by selecting the collection, then from the 3D Viewport menu choose Object > Apply > Make Instances Real or in the viewport hit Ctrl+A > Apply > Make Instances Real.

In the tool options on the bottom left of the viewport you can then choose if you want to parent the converted objects to the empty from which the instance came and if you want to keep the original hierarchy of the original collection when creating the individual objects. You can do this by enabling the options.
