Transmission gaps when APRS is selected in addition to MFSK_4 with RS41 device

I get a one minute gap in transmissions when APRS is selected in addition to MFSK_4. I tried changing a few of the settings, but the one minute gap didn't change. I was transmitting MFSK_4 every 5 seconds. When I deselect APRS, the gap in transmissions goes away.

Here are some tips for timing. I find only the default gps timing of 1000 fix rate and 1 for message rates will function. Secondly, for a combination such as APRS and 4fsk time the APRS at 60 seconds and use a post transmit delay to fit for example 6 4fsk transmissions into the minute. Time from end of last 4fsk must be greater than post transmit delay. This will be reliable. For example APRS 2 seconds, 6 4fsk 20 seconds. Leaves 44 seconds within the minute. Divide by 7 transmits gives post transmit delay of about 6200 ms.
