Bash paste -d “ ” command outputting a return separated file

问题

I am trying to combine two text files each with a single column into a third text file that has both of the columns separated by a space.

One text file looks something like the following (shortened for the purpose of this explanation):

-53.46
-50.45
-47.44

The second text file looks something like this (also shortened for this explanation):

1.71
3.42
5.13

and I want to combine them to get a file:

-53.46 1.71
-50.45 3.42
-47.44 5.13

Currently I am trying the method:

paste -d " " file1 file2 > file3

but then when I view the file with the less command the columns are separated by

^M

And if I view them in gedit or similar they are each on a different line with a space at the start of each line.

Please send help.
