Using apostrophe (') changes word!

[DJjay]

If I type, for example, the word mum then follow this by an apostrope (wanting to put an 's' after this), it will change 'mum' to 'nun', so I end up with nun's.

Similar to if I type the name Aaishah, which is in my custom dictionary, it will then change to Aagpgag'p !

Can we please correct this so when adding an apostrophe (and s) it doesn't change the preceding word?

Thanks.

Using phone keypad with T9 prediction.

If you're using the T9 keypad, you have to type in the entire word without T9 enabled. Otherwise it accepts the suggestion. This is the only way to add words to the dictionary when using the T9 layout.
