Xliff file import is creating a duplicate source string with unwanted spaces

[chaitanyaa64940]

importing new translation dictionary through xliff file , we are getting multiple rows of same source string , one has extra spaces , which we did not provide. extra row is added , but ideally they should merge with the same old string.
1.We maintained different ids , for source strings (different from those in translator.html page.)

aem version 6.5

Translation type : Manual Translations.
