issue (qt gui range) after uninstalling GR 3.9 and installing

I facing a simple issue on my Ubuntu 20.04 gnuradio install on one of my partition

I installed from ppa:gnuradio/gnuradio-releases on two different partition, both having Ubuntu 20.04 and the same PPA gnuradio version. Let's call these install P1 and P2: 

On P1, everything is working fine.

On my P2 second partition I get this error :

Traceback (most recent call last):
  File "/home/seguinot/Bureau/gilles_rubin/top_block.py", line 205, in <module>
  File "/home/seguinot/Bureau/gilles_rubin/top_block.py", line 181, in main
    tb = top_block_cls()
  File "/home/seguinot/Bureau/gilles_rubin/top_block.py", line 86, in __init__
    self._Offset_freq_win = RangeWidget(self._Offset_freq_range, self.set_Offset_freq, 'Corection frequence (ppm)', "counter_slider", float, QtCore.Qt.Horizontal)
TypeError: __init__() takes from 5 to 6 positional arguments but 7 were given

The error is simply caused by the last argument of the RangeWidget call: QtCore.Qt.Horizontal.

So the issue clearly lays in the python script generation.

Why is my P2 not generating the same top_block.py? It seems that There is something wrongly installed or some caching issue there (because of previously installed GR3.9 ?).  Does anyone could give me some hints to solve this?

I already verified that I only get one file for range.py a qtgui_range.block.yml

These files seems identical in P1 and P2
