It's difficult to say without seeing the scene (and in particular where you place the custom reflection point with the "Reflection control" effect).
In any case, the way to ensure that the reflections use a custom reflection point is to apply a "Reflection control" effect to your clip in Movie mode. Then select "Custom Position" and click on "Set reflection point". Move the camera to the position in your scene that you would like to use for the 360 degree reflection map, and click on "Back".
It sounds like you're already doing this, but perhaps you're not placing the custom reflection point in a suitable place? Try moving the position of the custom reflection point to various places in your scene. In some cases, you're also better off with "Land + Sky" reflections instead of "All objects".
When you're happy with the way the reflections look in Movie mode, go directly to Photo mode, since this mode "inherits" the effects/weather settings of whichever mode was last active (ie, Build or Movie mode).
In Build mode, reflections are only updated (once) when you change the weather settings. Alternatively, you can press (CTRL) + U to update the reflections manually. Build mode relies on the camera position for reflections, and all objects are reflected by default (well, apart from certain particle effects, but that's a known limitation). For that reason, some situations will require the "Reflection control" effect in Movie mode, since it allows you to choose whether you want a custom reflection point or not, and whether you want all objects to be reflected or just the land and sky.
