Reproducible on: Windows 11 Pro (22H2)
Not reproducible on: No other environment tested

Notes:
1. Does not reproduce if not using operators in the value field, for example “1,5”. Reproduces only if using operators “0+1,5”
2. Does not reproduce if using a dot instead of a comma
3. Reproduces in other Components as well, not just the Transform Component
