Problem on slot effect number 2

[curtistornade]

Hi !
Recently, I wanted to get all the plugin name on one channel in the mixer but I ran into a problem because it appears that the slot number 2 is not showing up correctly.
In fact, to test this error, I have put 9 Fruity Parametric EQ 2 on one channel (every slot except the third one) and one Fruity Reeverb 2 on the third slot of this channel.

Next, I ran this following script :

project = pyflp.parse(path)
    list_all_effects = []
    for insert in range(project.mixer.__len__() - 1):
        for slot in range(project.mixer.max_slots):
            if project.mixer.__getitem__(insert).__getitem__(slot).plugin is not None:
                list_all_effects.append(project.mixer.__getitem__(insert).__getitem__(slot))
                print('SLOT : ', slot+1)
                print('Effect : ', project.mixer.__getitem__(insert).__getitem__(slot) .internal_name)

And this is what I got :

SLOT 1
Effect :  Fruity Parametric EQ 2
SLOT 2
Effect :  Fruity Reeverb 2
SLOT 3
Effect :  Fruity Parametric EQ 2
SLOT 4
Effect :  Fruity Parametric EQ 2
SLOT 5
Effect :  Fruity Parametric EQ 2
SLOT 6
Effect :  Fruity Parametric EQ 2
SLOT 7
Effect :  Fruity Parametric EQ 2
SLOT 8
Effect :  Fruity Parametric EQ 2
SLOT 9
Effect :  Fruity Parametric EQ 2

As we can see, the Fruity Reeverb 2 is in this case showing on the second slot instead of the third one and there is no plugin detected on the last slot.
I have tested this with a Fruity Reeverb 2 on the second slot and this is the output :

SLOT :  1
Effect :  Fruity Parametric EQ 2
SLOT :  2
Effect :  Fruity Parametric EQ 2
SLOT :  3
Effect :  Fruity Parametric EQ 2
SLOT :  4
Effect :  Fruity Parametric EQ 2
SLOT :  5
Effect :  Fruity Parametric EQ 2
SLOT :  6
Effect :  Fruity Parametric EQ 2
SLOT :  7
Effect :  Fruity Parametric EQ 2
SLOT :  8
Effect :  Fruity Parametric EQ 2
SLOT :  9
Effect :  Fruity Parametric EQ 2

So it seems that the slot 2 is not read by the script and the following slots are shifted back by 1. Do you have any clue on this issue ?
Thank you a lot 🙏

To add some further information on this issue, I have tested the case where I insert an effect on SLOT 2 and SLOT 3 or more and there was no problem at all.
But as soon as I add something on SLOT 1, SLOT 2 is not processed by the script and it is the same problem as described before.

Send the FLP. Which version of PyFLP are you using? Why are you looping over the mixer and inserts with an index?

[curtistornade]

Here is the FLP file : parser_slot_test.flp.zip

I'm using the version 2.2.1 of PyFLP. And I'm looping over with an index because I didn't see the iterator method in the first place. But it is the same problem with the iterator too.

Thank you for your answer 🙏
