I was testing a form and came across this issue. If anyone can please let me know how to resolve this issue.
The scenario is, i have got a text field and set input type as "Number". When i preview it, it allows numbers and restricts alphabets except "E".
Try using a Decimal Field component and set the Decimal Places property to 0 if you are concerned about the "e".
I asked a similar question as well. The "e" stands for exponential which is a numeric symbol.
