Shrugging shoulders

[Amydoll]

Does anyone else have shrugging shoulders that also rotate forwards?
When I attempt to lift her arms up to change her top the shoulders also move forwards and feel like they lock into place so I have to try and push her shoulders back whilst lifting her arm whilst also trying to make sure she doesn't fall over.
Just wondering what technique to use as it's getting annoying. I do like them though as it does make her look more relaxed/natural
