I don't know if this is dupe, but I've made a search in the forum before posting.
I've been converting sub/idx packs to subrip format for a very long time. But sometimes I see that sth is wrong with timing structure. For instance:

---

1

01:23:16,076 --> 01:23:20,638

<i>I gotta own it, breathe it

Live it like I mean it</i>



2

01:23:00,021 --> 01:23:00,069

<i>There's a hero in me

It's all I wanna be</i>



3

01:22:54,829 --> 01:22:55,743

<i>Out of my way

This is a job for me</i>



4

01:22:36,078 --> 01:22:39,741

And our next book report is

from Jeffrey Zimmer.



5

01:22:25,087 --> 01:22:29,490

Well, my report is on Neal Morris'

new Tripp Zoome book,



6

01:22:06,039 --> 01:22:09,304

at this paper factory where they make

the paper that goes in the books.

480

00:01:17,967 --> 00:01:24,904

No police intervention.



481

00:01:15,351 --> 00:01:24,939

I promise.



482

00:00:57,079 --> 00:00:59,980

Bombs ready? Aim!



483

00:00:44,054 --> 00:00:45,851

This is just perfect.



484

00:00:29,099 --> 00:00:31,533

Come on! This will never come out!



485

00:00:15,095 --> 00:00:18,292

Merv Kilbo and his trusty ragtop

are on the case.

But it should be like this actually:

SW's "Timing Adjust" and "Fix Overlapped Lines" features didn't work. Is it possible to fix this making a script for SW or sth else?
I know it has nothing to do with SW. On the contrary it is completely related to idx file I got but I need to find out how I can fix this reversed timing problem.
Here is a sample complete sub, idx, and srt files of the example above:

Thank you in advance.
