Static Mesh extend like Venom

During development you should just stick with the most stable version with the least issues (often not the latest) such as UE4.26 / 4.27. When your project’s development is (nearly) done, you enter the testing stage in which you basically stop developing new features and start fixing any problems that are left (such as this one). At that point many people will have to test the end product so you can find out about issues just like these which in some cases only a few people might be experiencing. So for now you have nothing to worry about.
