Generated target file contains multiple translations from TM

I use Trados Studio 2015 and encountered a weird issue.

After completing translation I saved a clean file with translation (using Generate Target Translations option). Everything went smoothly, no error messages. But when I open the file, they are not 1:1 translations.

1. Some of the source segments have previous translation stored in TM but not 100%.

2. All segments were newly translated.

3. The target file I generated after completing translation contains 3 translations lined up in a row for each segment. 2 identical fuzzy matches with the actual translation. They basically look like double copy-pasted, without space between those 3 translations.

Fuzzy match 1.Fuzzy match 1.2. My translation 1. Fuzzy match 2.Fuzzy match 2.1.My translation 2. and so on...

When I was working in Studio, there weren't fuzzy suggestions so I didn't even know there were any. There were no repeating sentences in sdlxliff file for them to be included. The Studio applied fuzzy translations while generating the clean file, for some reason. I had another file for the same package, which came out fine, but I suspect it is because there was no fuzzy matches to apply...

For this project I just copy-pasted my translation from Trados to the original word file, since the volume was small. I just don't want this to happen again later, or want to at least know how to resolve it other than manual copy and paste. Any insights will be great!
