What information are you using for programming the repeaters?
For a repeater you'll need frequency, offset, and PL tone if enabled. https://repeaterbook.com is a good online resource and mobile app.
When you transmit, watch the frequency display and make sure it's changing either up or down based on the offset.
If it doesn't then you are transmitting simplex.

My last 2M xcvr had option for one PL Tone but back then it wasn't necessary (long time ago).
That radio began changing frequency to 144.000 and couldn't be repaired
