Is tethering after a brow lift normal?

Dear Doctors, I have an APTOS brow thread lift around six weeks ago. It has never looked good as there is a lot of tethering in the middle and outer edges of the brows. It looks very strange, it's not subsiding and feels very lumpy. Please can you advise if this is normal and if so, how long it takes for things to settle? I have watched numerous brow threading videos and none so far has been left with this unevenness and tethering. Thank you so much.
