Titan One (7.2) on an acer (Win

Recorded a load of position palettes, normal mode, Masked to P - they work fine.
Recorded a load of position shapes, normal mode, Masked to FX - they work fine.
Close and re load the show and half of the position shapes will forget their mask so in effect become useless palettes.

You can see here, all my shape palettes. Before the Show was reloaded they all had FX include masks only, reloading the show and half of them randomly have 'forgotten' their masks.
Is this a bug?
