I just double checked the files, all three 2da files are the UNMODIFIED original files within this tslpatchdata. Therefore, the cause of your issue is not stemming from the tslpatchdata folder, nor the installer's handling of the 2da files. It is possible that other mods are conflicting with this, or you may have not installed another mod correctly that did a similar thing (modified the same files). I'd suggest trying to get some help with a forum post, /r kotor post, or /r kotor discord channel, to find out what went wrong.
