Special characters inside columns' titles but not true (Warning Table Badname)

[DroidTeo]

I'm receiving the following message:

Table name 'IINR(finishes)' uses special characters that are used in expressions and formulas. Consider renaming the table to remove these special characters.

But I checked and there are no special characters inside any title.
I also tried to create a new app using a different GSheets, in which a copy paste the titles of the columns and in this case, no warning message.

What can it be the reason?
Can I reset the error message in somehow? 
Thanks!

Hi @DroidTeo Its actually the Name of the Table that contains special character "()". Consider renaming the table without any special characters. 

One more this I wish to add is that you have wrongly posted this question in Tips & Tricks section instead of Q&A
