Thanks for the report,
It has been fixed now in the newer versions. The mod will now inject the file n_darthtraya001.utc to the appropriate module file. So that it will only take affect when arriving at Malachor V.
For non TSLRCM users though, they will have to follow the instructions to manually install the mod, provided in the ReadMeInstall.txt that comes with this mod.
I was having the same issue - renaming the two files w_ionrfl_04.mdl and w_ionrfl_04.mdx to w_ionrfl_004.mdl and w_ionrfl_004.mdx (like all the other ones) seems to solve the problem
