I can not change the object's layer

[oct1024]

This autocad mechanical 2015

This is the original state of the object

I am ready to change the layer

Objects can be previewed right

After click

Layer Properties Manager appear

Close the Layer Properties Manager

Current layer has changed.

But the object does not change!

How to solve the problem?

Hye oct1024,

I'm trying to check with you first. Do you have to select that object before change the layer?

I do not understand what you mean.

I do not know if this is necessary, but I am used to first select the object before changing layers.

This problem did not occur in previous versions.

This problem does not always exist.

But it often occurs.

The moment is normal, the next moment it happened.
