Issue with multiple virtual pin read in Python

Solved
1

I am observing strange behavior of the virtual pin read event handler in python. Here is the case:
HW is Raspberry pi. In the app:
One “Numeric Input” widget on virtual pin 10 (get volume to be pumped)
One “Value display” widget on VP11 (display how long will take the pumping)
One “Button” widget on VP12 to trigger the pump
One “Value display” widget to show,when pump has been turned on, how much time is left before it is turned off.

The code here below works fine for pump1.
The second part of the code is the exact same code with pump2 on VP14-17 but for some reasons, the value display widgets are not updated (the events are not handled).

Any idea ?
Thanks

Please edit your post (using the pencil icon) and put the correct triple backtick characters at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
