The problem is the dot after the plus. Your regex will find things like 123x., because . matches anything:

123 x .
^^^ ^ ^
 |  | |
 |  | +-- \.
 |  +---- .
 +------- [0-9]+

Remove the first dot to fix this.

Remove the in-between unescaped dot. Because an unescaped dot in regex matches any character.

[0-9]+\.
