Microsoft Excel glitch

[hrking2000]

I was wondering if anyone has noticed the following issue with MS Excel - when inputting a formula eg "=123" the first number deletes automatically and it shows "=23".
It is a pretty odd issue happening on my phone and was wondering if anyone else noticed it? Was wondering if it is just me or a S6 edge specific issue or a wider issue?

Does not happen to me. "=123" shows properly as "=123". I've heard of certain 3rd party keyboards causing such problems.
