Unable to search in columns containing numeric values

What causes this issue?

The functions 'Find' and 'Find next' can only be used with columns that
contain non-numeric values. Note that a number of values that look like
numbers (account numbers, dates and times, etc.) are considered to be
non-numeric values.
