Since you say it is in good health (everything is together) then i think it is a flow issue.
IMO i would not "contain" it within a plastic container, this will do nothing but stress the animal out - then you may have a dead anemone on your hands. THe issue isn't b/c the anemone is so picky that you need to try and force it to settle - make sure your PH intakes are covered and let it roam until it settles itself. Again if it takes more than a few days (5 or so) then i would mixup the flow and rocks.
Also you say you have ideal water parameters - but give us the real numbers. 0 nitrates and a high salinity of around 35.
The keyword here is "attaching" to LR if the anenome is not attaching at all it is the sign of not healthy/stress anenome. If it is attaching to LR, by all mean let it roam .. if it is not attaching, flowing/rolling on the bottom, you are risking it to be stuck on something and rip its body .. Using a plastic container with "good flow" will not stress the anenome, with additional note please consider the size of the container in relation to the anenome. Just because the tentacles are inflating/blomming it is not a sign that aneome is 100% healthy if the body does not attach to glass/LR.
