Regex finds comma wenn searching for period

Hey there,

I wanted to use regexReplacer in the String manipulation node to remove periods in numbers, so for example: 1.000 → 1000

I used the following regex for this operation: regexReplace($Value$,“([0-9])\.([0-9])” ,“$1$2” )

Now, according to https://regex101.com/, this should yield the correct values, and it does. However, it also removes commas: 3,5 → 35

This should not be the case. I have attached the workflow. I work on Windows 11. My KNIME version should be up to date: KNIME 5.7.0.
