Studio One 6 tempo /ruler question – Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) Forum

When I go down to where the transport buttons are and change the tempo from say, 100 to 120,the ruler/bar beat thing at the top also changes. It goes closer together or farther apart depending on the tempo change. Can I just change the tempo without anything else being triggered to respond to it? I just noticed it recently so I’m guessing I clicked a wrong box somewhere.
I’d appreciate some help.
