The bank you referenced has had many challenges in their operations starting clear back to 2015 and has been cited by Federal Agencies for their not running in accordance with best practices and required banking rules (if that is what it is called).
If my memory is right, the San Antonio Express-News is one that wrote the bank up. For reasons unknown to me, the challenges to the bank did not really hit the big news. Also, Google is our friend and reading the actual Federal Reserve Reports is ever mind boggling. 
The bank has paid out millions in fines over the last few years. Elsewhere in this Forum there were postings on the bank. Your findings match mine!
For myself, I walked away to a different bank after reading about the bank's mis-management of customer information security which was reported in March-April 2022. Heavy fines were again levied. Like another very major bank this one needs a good cleanup (house keeping) or closing 
In summary, it was not good.
