Form Controls was duplicated

[HoangNguyen]

My Excel Workbook has macro, a few buttons, checkboxes on it. After recently patched in April 2018, some how all form controls was duplicated with same Name but different msoType. One is type 1 (invisible) and the other is type 8 (visible). So when I click any button or checkbox that try to set value of another checkbox, it will error that form control is not found. Because there are 2 identical controls on same worksheet. I have to write a for loop to delete any form control with msoType 1 and the VBA part will work as normal. Do you know what did latest patching do to create this problem? Do you have any fixed or solution for this? Thank you very much.
