Sorting the table by text column. Undesirable results

OS version: Windows 10
App version: ONLYOFFICE Desktop Editors v. 6.4.2.6
Downloaded from: ONLYOFFICE website

The first column in my table contains the room numbers, in text format (numbers mixed with letters).
For example: 101, 101a, 101b, 201, 202, 202b, 301, 302
After sorting by the first column, I get a column in the form: 101, 201, 202, 301, 302, 101a, 101b, 202b

Why?

In MS Excel, the result is correct.
