Impossible to set original story points

[Jérôme Laurent]

Hi!

I want update Original Story Points in the portfolio screen.
When i commit, i have the error message : '11.0' est un nombre invalide

The field type is com.atlassian.jpo:jpo-custom-field-original-story-points

Have you ever seen this issue ?

Production version is 3.19.1 and Integration version is 3.29.4 => same error

Jira version is 8.7.1 server.

Thank you.
