Need help with my own personal Interface / Addon

[Daywrecker]

I am using 2 macros to move MultiBarBottomRight to the Center of the screen just under my character.

/run MultiBarBottomRight:ClearAllPoints();
MultiBarBottomRight:SetPoint("CENTER",0,200);
UIPARENT_MANAGED_FRAME_POSITIONS["MultiBarBottomRight"] = nil;

/run MultiBarBottomRight:Show()
/run MultiBarBottomRight:SetScale(1.2);
/run SetCVar ("nameplateSelfTopInset", .54)
/run SetCVar ("nameplateSelfBottomInset", .40)

This looks something like this:



However the bar keeps vanishing, sometimes moving between doorways, sometimes when attacking players.

I do not have this problem if I turn on "Interface > ActionBars > Bottom Right Bar" but that then looks untidy:



Please help!
