If happened at 134 kts, either the flaps were not 100% fully retracted, or some random x-plane failure kicked in.
If you look the flaps limits placard, there are values for each flap position (per 1/4). Those limits are for flaps being stationary. Also the bottom line says "EXTENSION 97kts", which means that you should not try to extend at all, even a tiny bit, if you speed is much higher than 97 kts. All limits have some leeway though. You might extend the flaps at, for example, at 102kts and nothing will happen, but do not push your luck too much.
At the end, we left the option to be able to reset the failure, not to make you flight more challenging than anticipated.
