Please Help me with the question below - remove number

Help requested please

Tags shown: File name and Title (example)

(there are no spaces between 1.Lights)

Editors - 1.lights 1.lights

This should be like this:

Editors - Lights Lights

The 1 stands for number 1 of course, but also applies to all the other songs on the album

Thank you very much in advance! Elie

Try Convert>Tag-Tag or an action of the type "Format value" for TITLE:
Format string: $regexp(%title%,\d\.,)

Maybe the slightly enhanced format string
$regexp(%title%,\d+\.,)
would be a better fit, especially if the OP has numbers with two or more digits like in the example:
Editors - 10.lights 100.lights

The \d+\. would replace any number of digits followed by a dot, with "nothing" = remove them.

Thank you very much for the quick and beneficial answer.Thanks to you my problem has been solved and that is of course fantastic, I am very grateful! Elie.
