This phenomenon has appeared since the July 2022 update.
Here is my checked ver.
7.3 -> none
Steps to Reproduce:
3.Open sorting option>sorting oreder
2.Open tool>option>LOC>order list
User Profile Reset: No
The number of times the list grows seems to be random.
At 220.127.116.11 it seemed to proliferate with every start LOC.
At 18.104.22.168 is seemed to proliferate twice(see Actual results)
