Hello,
There are no such known issues and I am not be able to replicate the issue at my end with the latest version of Spread i.e. Spread for Winforms v7.35.20132.0. I would suggest you to test the issue with the latest build which you can download from the following link:

Hope it helps. However, if the issue still persists, I would request you to share a sample application depicting your issue so that I can debug it further.
Thanks,
Manpreet Kaur
