I reproduced it. The problem is that the duration of other filters on the clip are not automatically adjusted to the freeze frame duration. If you look at Keyframes for one of them and zoom into its timeline, you see something like this (red bar shows the filter ends before the clip):
This is somewhat related to Trimming Filters that also explains the workaround. Click >| to go to the end of the clip and then click or press ] to adjust the filter to end when the clip ends instead of earlier. Now, if you extend the frozen clip to make it longer the other filters are also extended.
