Normalized phones not visible in client

Hello all,

we updated the client to Skype For Business and in this client don't see 5-digit numbers in contact cards.

We have a lync 2010 server,  
For users we set Work phones as internal 5-digit number
On server we have a file Company_Phone_Number_Normalization_Rules.txt with the text:
(\d{5})
$1

Everything is ok with lync 2010 client and lync 2013, but when we updated to SkypeForBusiness client those numbers are gone.

Are there in solution/fixes for that?

thank you
Best Regards,
Anton
