Hi natosha
I have tried using your files. I am able to delete any keyframes from any of the objects you set with keyframes.
This tested OK in both Lumion Pro 2.5 and Lumion Ultimate 2.2.1
Some further options to try:
1. if you only need linear paths, maybe use Basic Animation Effect which only require the start and need keyframes.
2. I have attached your scene files as re-saved files (no other changes), just in case the problem is file based but doubt it, but it is worth a try.
3. Also, can you check that you do not have Enable Tablet Input turned on, and advise what sort of mouse you are using.
