Martxa fix request - javascript error

Hello Colorlib Support,
we encounter javascript error in Martxa template and the script is minified so you are our last chance to fix this.
This is the website I am not sure, that it is required, but I saw other people post it.

Error is in funfact-area and it occurs when you scroll fast up and down .The funfact-area must be moved outside screen view and when it comes back there is this error and all the values become zeroes.
Error:

Uncaught TypeError: Cannot read property 'shift' of null
    at c (counterup.main.js:8)

it is related with setTimeout(async) function.

Thank you in advance for your help.

Hello,

I hope you are doing well today.

When did you notice this issue?

Also have you added any new code that would affect the java script?

Best Regards,
Support

Hello,
I notice it few weeks ago.
And no nothing is changed there only numbers and texts, but I found this issue before changing texts.
Even the image is not changed.

The issue occurs only if you scroll up to hide fanfact-area and then fast scroll back down to show fanfact-area.
I think that it is happening when the animation is not over and you invoke the animation again.
Development console output is:

Uncaught TypeError: Cannot read property 'shift' of null
    at c (counterup.main.js:8) 
    setTimeout (async)

Good eveing

Svetliott what i have not tried but the problem is not happening for me, can you share the screenshot of the error message? also, is any functionality affected by this error or warning?

Here are screen shots taken from original theme address preview.
Functionality is affected because the numbers that are shifted become zeroes.
You will see on the pictures
Picture 1 and 2 are normal state.
After that are the steps of error. The numbers are going down to zero.
Example: Photoshop: 1200 - normal
Photoshop: 0 - Error
