Time Signature Change Causes Incomplete Measures

Greetings Musescore Forums,

I just started using Musescore today, and I'm having an issue with a specific time signature change in my score. In the bass clef of bar 7, the only placeholder rest for the measure is an eighth rest. If I were to place a whole note, it would prolong the note across the next measure. Also, in the treble clef of bar 9, it only allows me to place 4 eighth notes, although the time signature is in 4/4. This may be a bug or just a rookie mistake. Any help would be appreciated! I'm on version 1.3 which seems to be the latest version.
