Changing layer of a railing, bug?

[ReignBough]

When I change the layer of railing element (AC21) using ACAPI_Element_Change() funtion, the railing changes its appearance. My code:

API_Element elem, mask;
BNZeroMemory(&elem, API_ElementSize);
ACAPI_ELEMENT_MASK_CLEAR(mask);
ACAPI_ELEMENT_MASK_SET(mask, API_Elem_Head, layer);
elem.header.guid = /*railing element guid*/;
err = ACAPI_Element_Get(&elem);
elem.header.layer = /*new layer index*/;
err = ACAPI_Element_Change(&elem, &mask, NULL, NULL, true);

Hello,

thank you for pointing out this issue. Unfortunatelly it's a bug in our API.
We are working on the fix and hopefully it will be fixed in an upcoming update.
