relative values bug using MAtricks transform:mirror ?!

hey folks, i am pretty desperate. i am using grandma3 on PC 1.8.8.2. both presets were built from scratch no sequence runnig, just pure values in the programmer. i built 1 absolute preset pointing towards the wall, stored it, everything ok. cleared programmer...then i built a 2nd preset. same fixtures, a relative circle. and here came the frist problem. as soon as i added my first relative point in the phaser editor, on tilt axis, the absolute layer got activated(for no reason at all). a can live with that an switched off the absolute layer and stored that relative circle preset.

so now i have 2 presets. a "wall" preset and a "circle" preset. both consisting of either pure absolute or pure relative values.

and what happenes now is a miracle. when i double click on my wall preset, my 10 fixtures get selected and point towards the wall, when i now once click onto the circle preset i create a look.

now i clear out the programmer and i double click onto my wall preset and then double click on my circle preset and the look is different...that shouldn't be.

so what i realize when i look into my programmer window and check out my relative values of the circle preset: every fixture which got it's values from the 'tranfsform mirror" option in MAtricks has got a zero value on the pan attribute instead of the preset name written in the fixture sheet...i added some screenshots:

and the story doesn't end here. when i double click on the wall preset and single click on the circle preset directly afterwards, the values get stored into my cue as expected.

but when i double click on the wall preset and double click on the cirlce preset directly afterwards, the values get stored into my cue, but not the pan/tilt value from the absolute wall preset. the relative values from the circle preset seem to equalize it...

that is so strange!

Andreas thanks for explaining. that feature drove me crazy...
