iphone trello card text revise error

[Lena Lee]

I use iphone and the following error occurs

“re-editing the card title”

(see below)

ex)

Card title : 15:90 apple

I need to revise the time to 15:00 above.

When I place the cursor between 9 and 0 and click the DELETE key,
the cursor jumps to the end of the title apple (cursor jumps to the last place after “e”)

This error continued for about 2 months. I am a premium paid user. 

Please fix this error.

Thank you.
